Mac2008

Below are Christopher Brooks' Mac notes from 2008-2011. See Mac for more recent notes.

Getting Started with a Mac

So, ya bought a Mac. Below are some pointers

What we have

Apple MacBook Pro 15-inch, 2.4GHz MB113LL/A includes base price 3-year warranty, Sadly, Apple continues to ship hardware that does not have part numbers. Going to the Apple site and searching for the manual by the serial number finds Mac Book Pro Early 2008 UserGuide

UI Pointers

• To get a context menu, or what is a right menu button menu under Windows, hold the Control key and then click.
• To get a context menu under Windows Remote Desktop Connection, hold both the Shift key and the Control key and then click.
• To install applications, MacOSX has this peculiar standard for installers that wants the user to drag the icon of the software to the application icon in the installer.
• The delete key is incorrectly labelled, it is actually a backspace key. Try Fn-delete and other fixes
• To become root, use sudo -i -u root

Problems

• The MacBook Pro 15" has really crappy wireless network performance. Apple would probably lose a class action lawsuit on this one . . .
  • Rumor has it that it is because of the aluminum case. Apparently the Mac is supposed to get wifi via the rubber area near the hinge. This problem has been seen in other MacBook Pro 15" machines as well
  • Apple Support: Is Macbook Pro wireless just plain weak?
    • Quickertek FAQ says "How come the PowerBooks, MacBook Pro, etc. have bad signal quality compared to PC Notebooks and Laptops? Because the of the placement of the antenna’s behind the metal case and lower than usual output power from the AirPort card inside the computer."
  • Symptoms:
    • This machine was outperformed by a 3 year old bottom-end Dell in that the Dell could get a wifi signal in a hotel room, but the Mac could not.
    • I get 3 bars even if I'm within 2 meter of the Netgear WPN824 hub.
      • In "b only mode", iStumbler shows

• In "g only mode", iStumber says:

• I get 4 bars if I'm within 2 meters of an Apple Time Machine
  • TimeMachine in "802.11n (802:11b/g compatible)
    The AirPort Utility says Signal -60, Noise -91, Rate 104

• TimeMachine in "802.11n (2.4GHz)
  The AirPort Utility says Signal -60, Noise -91, Rate 130

• TimeMachine in "802.11n (802.11a compatible)
  The AirPort Utility says Signal -60, Noise -91, Rate 130

• TimeMachine in "802.11n (802.11a compatible)"
  The AirPort Utility says Signal -53, Noise -90, Rate 270

• TimeMachine in "802.11n only (5GHz)"
  The AirPort Utility says Signal -59, Noise -90, Rate 270

• Possible solutions:
  • Placing the AirPort connection first in the list may help
  • Zapping the PRAM may help
  • MacBook Pro Wireless Problems Solved, Update #2 - Hardware repair of a MacBook Pro. Used Antenna Part $29
• Adding a wireless card Express34 card?
  • Mac Book Pro Early 2008 User Guide says that the Mac has an Express34 wireless card.
  • Quickertek Expresscard $149.95 802.11/b/g/n not 802.11n 5Ghz or 802.11a compatible. "This card is best used without an Apple AirPort wireless card installed" iStumbler does not see the card, but other software does
  • Encore ENUWI-N 2.4 Ghz only, ot 802.11n 5Ghz or 802.11a compatible. Not listed with Mac Drivers?
• USB Wireless - there are lots of these
  • Quickertek nNano $89.95 802.11/b/g/n, not 802.11n 5Ghz or 802.11a compatible

    • Quickertek nNano started crashing

Fix: http://www.ralinktech.com/ralink/Home/Support/Macintosh.html and download http://www.ralinktech.com.tw/data/drivers/RTUSB%20D2870-1.3.0.0%20UI-1.7.1.0_2009_03_10.dmg for the USB (RT2870/RT2779/RT307X)" RT28xx:1.3.0.0. Update: The Quickertek nNano is still unstable and crashes regularly on startup. I'm stopping using it and ordering another nQuicky.

• Quickertek nQuicky $149 802.11/b/g/n, not 802.11n 5Ghz or 802.11a compatible

  • hField Wi-Fire $79
• Antennas
  • Quickertek 5.5 dBi Antenna for MacBook Pro 15" $79

• There is no way to hibernate the machine, only sleep it, which consumes battery power.
  • Fix: Recent MacBooks have safe sleep. Deepsleep is a Dashboard widget that will hibernate the machine.
• How do I get more information about the wireless signal strength?
  • Fix: Download IStumbler, which should be part of Mac OS X
• How do I get more information about the Apple USB Modem connection rate?
  • Workaround: Look in /var/log/ppp.log for lines like

Setting up a Mac for use with Ptolemy

1. Update to the most recent version of the OS by doing Apple | Software Update
2. Install Xcode from Apple, which includes gcc and other tools. Xcode is a 1 GB (!) download, and might not be required.
3. Install Java Extensions - Several extensions were already installed, others are not available for the Mac. Below is a description.
   1. Java 3D - No need to install, the jars are already in System|Library|Java|Extensions, (j3daudio.jar, j3dcore.jar, j3dutilities.jar and jnilibs)
   2. Java Communications API 7/16/08 - Could not find download. Sun is no longer supporting the Java Communications API, try rxtx
   3. Java Media Framework - Select the Linux download and then select the cross platform version. See JMF on OS X for hints.
      unzip JMF-2.1.1e-alljava.zip
      sudo -i
      cp JMF-2.1.1e/lib/*.jar /System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home/lib/ext/
      cp lib/*.jar /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/lib/ext/

      [$[Get Code]]
      Note that it seems that is not possible to use the video camera with JMF. The jminit script runs the JMFInit class that is found in jmf.jar. The source for JMFInit indicates that it searches for classes like VFWAuto, SunVideoAuto and SunVideoPlusAuto. These classes are not found in the jmf.jar file shipped with jmf-2_1_1e-alljava.zip
   4. Java Advance Imaging - No need to install, already in System|Library|Java|Extensions (jai_codec.jar, jai_core.jar) - Note that JAI is not available for the Mac from Sun.
   5. QuickTime for Java - Already installed in System|Library|Java|Extensions (QTJava.zip)
4. Install Eclipse, see the ptexternal page

Restrictions about Versions of Java

1. Eclipse 3.4.0 will not start up for me under Java 1.6.0_05 on the Mac. This means that if "java -version" returns 1.6.0_05, then Eclipse failed to start for me.
2. Within Eclipse 3.4.0 which was started with Java 1.5.0_13, you can compile and run your project with either Java 1.5.0_13 or Java 1.6.0_13.
3. Eclipse 3.4.0 Java Projects that include Eclipse Plug-ins don't work under either Java 1.5.0_13 or Java 1.6.0_05 on the Mac

Running Eclipse under Java 1.6

It appears that Eclipse 3.4.0, Build id: I20080617-2000 does not work with Java 1.6.0.

On my Mac with these settings:

Eclipse 3.4.0 works fine under Java 1.5.0_13 under Mac OS X.

If I change from Java 1.5.0_13 to Java 1.6:

Eclipse fails to start under Java 1.6.0_05 under Mac OS X:

Thanks to Patricia Derler

Problems with Eclipse and Ptolemy on the Mac

This problem is solved by modifying configure, but the details are interesting. The solution is to not have projects that have plug-ins in them.

Running Eclipse 3.4.0 with Java 1.5.0_13, I get a stack trace involving HTMLViewer

This error does not occur when running from the command line.

A workaround is to use Java 1.6.0_05. However, then the splash screen comes up and hangs.

• It looks like the main thread quickly exits
• I tried using .classpath.default by copying that file to .classpath
• Running ptolemy.plot.moml.EditablePlotMLApplication has similar problems
• If I replace invokeLater() with invokeAndWait() then I get a grey box and see this

I see the above for both VergilApplication and EditablePlotMLApplication if I use invokeAndWait()

• Interestingly, creating a project from the PtPlot5.7 sources works fine - the binary runs.
• Another symptom is that when starting Vergil inside Eclipse with Java 1.5.0_16, the following messages may appear in the console:

and then Vergil fails to start up.

• So, really, the problem is that if the Eclipse .classpath has

then I get the hanging problem.

The workaround on the Mac is to configure with:

and then edit .classpath and remove

configure has been modified so that under Mac OS X, it does not include <classpathentry kind="con" path="org.eclipse.pde.core.requiredPlugins"/> in the .classpath for the ptII project and does not attempt to compile ptolemy/apps/eclipse/awt or ptolemy/backtrack in the ptII project. Note that ptolemy/backtrack can be compiled outside of Eclipse on the Mac by doing cd $PTII; ./configure; make, the problem is compiling backtrack within Eclipse.

32 bit Java vs 64 bit Java

JVMs are either 32 bit or 64 bit. This matters when we try to link with native shared libraries in the standalone Ptolemy Application, Web Start and signed applets. (Unsigned applets cannot load native shared libraries. The Ptolemy website uses unsigned applets.)

Under Mac OS 10.5, Java 1.5.0_22 is 32 bit, Java 1.6.0_17 is 64 bit:

To run a 64 bit Java 1.5, use -d64:

The Java Preferences utility displays which JVMs are installed. To bring up the Java Preferences utility, use: Applications -> Utilities -> Java Preferences. Below is a screen shot of the Java Preferences in Mac OS X 10.5. Note the versions of the JDKs and the order

Use the Java Native Interface under 64 bit Java 1.6

• simpleJavaLauncher - code that invokes Java from C.
• Re: simpleJavaLauncher with Java 6 - discussion about 64 bit Java and simpleJavaLauncher

Using simpleJavaLauncher with 64 bit Java 1.6

1. Download simpleJavaLauncher.zip from http://developer.apple.com/library/mac/#samplecode/simpleJavaLauncher/Introduction/Intro.html
2. Unzip it
3. Compile
   gcc -m64 -o simpleJavaLauncher simple.c utils.c -L$(/usr/libexec/java_home)/../Libraries -ljvm -L/sw/lib -framework CoreFoundation -framework IOKit -lserver -framework JavaVM
   javac HelloWorld.java

Web Start problem with rxtx

rxtx is a Java serial package

Under Webstart, I was getting:

The problem is that Web Start is running a 64 bit version:

but the libraries are 32 bit

• Surveyor.com page that discusses the issue and links to a 64 bit library

Configuration Issues

Setting the path

The default shell is bash. When you log in, ~/.bash_profile is read. When a remote command is invoked, say via ssh, then ~/.bashrc is invoked. In general, ~/.bashrc should not write to standard out. One trick is to create ~/.bashrc and then create a symbolic link from ~/.bash_profile to ~/.bashrc:

A typical ~/.bashrc might look like

Issues

Below is a list of issues we ran into

iCal

iCal is the Mac OS X Calendar tool.

iCal and Oracle Calendar

It would be nice to be able to use both iCal and CalAgenda (which is really Oracle Calendar).

See also Micronet 10/08 posting: iPhone and CalAgenda

Oracle calendar has many problems, the biggest is that the Oracle Calendar Windows client 10.1.2.3.0.398 exits when it loses its connection with the server. Obviously, the author of this program does not understand the client/server paradigm.

iCal is not an enterprise solution, it does not make it easy for others to edit events etc.

In the perfect world, anyone could use any client to view, add, modify and delete events on any calendar for which they had the appropriate permissions.

However, Oracle Calendar Windows Client 10.1.x does not support easy roundtrip access from iCal and back. It is possible to export and import iCalendar .ics files, but there could be problems with duplicate events and with events being overwritten.

Downloading data from Oracle Calendar to iCal by using the iCalendar format and creating a .ics file is easy enough. However, changes made in iCal will not be propagated back up to Oracle Calendar and downloading multiple times could result in duplicate entries.

• October, 2006 MAGnet item by Aron Roberts lines out two ways to do a one way download from Oracle Calendar to iCal. Howevever, this does not mean that changes on Oracle are transmitted to iCal or visa versa.
  • Export from Oracle Calendar to iCalendar, which creates a .ics file, then read the file into iCal
  • Use the Oracle Calendar API to access the calendar
• There is also OraCal2iCal, which uses accessibility to automatically export the calendar from Oracle Calendar and import it into iCal. This is a one-way solution, not a round-trip solution. The OraCal2iCal website says:

CalDAV

CalDAV is a standard that allows the sharing of scheduling information.

• In the ideal world, Oracle Calendar would work with CalDAV. However, the current 10.1.x Oracle Calendar Client does not work with CalDAV. Oracle Beehive does work with CalDAV, but Oracle Beehive is not what is in use on the Berkeley campus (9/08).
  • Jan 2008 Oracle Forum article - Says that Oracle Beehive will support CalDAV
  • August 22, 2008 UCB IS&T article "Next generation of CalAgenda"
• iCal works with Apple's iCal Server.
• Google Calendar CalDAV support

Read-only access to iCal calendars

To share a calendar, use the currently free website http://www.icalx.com.

1. Go to http://www.icalx.com and register for an account
   1. Log on to http://www.icalx.com, select passwords and create an account and password to give to the person with whom you want to share your calendar.
2. In iCal, go to Calendar|Publish,
   1. Select Publish to a Private Server
   2. Enter the BaseURL of your calendar, something like http://icalx.com/private/yourlogin, where yourlogin is your iCalx account name (not the name and password you created to give away)
   3. Select Publish changes automatically
   4. You will then be prompted to send email to people who want to subscribe to your calendar. Your calendar will be at an address like webcal://icalx.com/private/yourlogin/Work.ics.

Below is a screenshot of the Publish window

Troubleshooting

• Go to http://www.icalx.com/account.php and check the 'last published' date.
• In iCal, try Calendar -> Refresh All. Then check that http://www.icalx.com/account.php has updated.
• If the 'last published' date and time does not update, then in iCal, control-click on the account name and select 'Change Location' and make sure that the settings are as above in Read-only access to iCal calendars

I found that Publish changes automatically had become unselected?

iCal hangs

iCal was consuming lots of CPU and hitting the disk hard (writing 6Mb/sec). The Activity Monitor shows iCal (Not Responding).

• Apple Support Discussions: Topic : Leopard iCal "Calendar Cache" subscription refresh bug persists in 10.5.3 Suggested removing ~/Library/Calendars/Calendar Cache.
• http://www.macosxhints.com/article.php?story=2007091913425840 from 2007 that suggests running iSync or dumping and restoring.
• Apple Support Discussions : iCal 'not respondg' aftr left power off. Reset dateOK. All else OK.Pleas suggests removing ~/Library/Preferences/com.apple.iCal.plist

USB Scanner

I have an old HP ScanJet6300C that has a USB connection. Unfortunately, Mac OS X drivers are not available for it.

• http://www.ellert.se/twain-sane/ - Twain Sane- Worked for me, though I had to install several packages from that site and reboot to get it to work.
• http://www.hamrick.com/ - Vuescan - Not free, but also worked.

USB Printers

Getting USB Printers to work can be difficult. Mac OS 10.5 (Leopard) includes drivers for many printers.

• Mac OS X 10.5.3: Printer drivers included in the HP Printer Driver Update v1.1 - Includes support for LaserJet 9040, but not DeskJet 6127 or DeskJet D145. I did not knowingly install this.
• HP LaserJet Mac OS X Installer Print Only Software Solution for v10.2, v10.3.x, v10.4.x, v10.5 - I installed 7.8.0.761 (28 Jan 2008)

HP DeskJet 6127

I googled HP deskjet 6127 Mac OS. The page that came up had a link at the bottom for Mac OS 10.5 that said to just plug the printer in. http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=c01234224

What I did on my machine was plug the printer in and the driver was there.

I was able to print.

To print double sided, I had to select a different paper size, there were two sizes for US Letter. The wrong one was US Letter Banner. It looks like the driver to use is not the gutenprint driver, which is what is included in Mac OS X 10.5. I believe the driver that did work came from HP LaserJet Mac OS X Installer Print Only Software Solution for v10.2, v10.3.x, v10.4.x, v10.5

HP Officejet D145

• Apple Support Discussion - was not able to get duplexer to work

• HP Officejet Full Feature Software and Drivers - Mac OS X v10.3.9, v10.4 and v10.5 - "for a different printer, and it won't install

with my printer (doesn't recognize the printer model)."

• HP OfficeJet D145 Drivers - does not mention Mac OS X 10.5 - "already installed, and it doesn't support double sided"
• HP Print Drivers for Mac OS X v10.5 (Leopard) -

indicates that the OfficeJet D145 only has a gutenprint driver built in to Mac OS 10.5.

• hpijs supports the OfficeJet D145
• 2004 note about getting D145 duplexer working

Conversion of Eudora from Windows to Mac

Converting Eudora Mailboxes from Windows to Mac OS X was rather difficult.

• A Windows expert opts for a Mac life, Part 2 - ComputerWorld article from December, 2006

Migrating From Windows to MAC from the Eudora site seems to be about moving towards Mac OS 9, not Mac OS X. It may have been necessary to convert the end of line characters using flip. Note that Mac OS X uses Unix end of line characters, not "Mac" end of line characters. It turns out that the key was to use the Mac OS X command line program GetFileInfo to get the type, attributes, and creator codes for a Eudora-created mailbox and then set them for copies of your mailbox using

Showing hidden files and directories like /tmp

The Mac OS X finder does not allow one to browse to directories like /tmp. See Show All Files in the Finder

Problems deleting .svn directories

When I check out a repository in Eclipse using either Subversive or Subclipse, I can't delete the repository from the shell.

It seems like only running either Subclipse or Subversive from inside Eclipse has this problem. Repositories checked out by the svn command does not. What I was doing was checking out the triq repository and then importing the projects into a workspace. Subclipse 1.2.0 (Feb. 2007) suggests that this is a problem. It looks like this has been a problem since 2006. Re: Resend: .svn/entries getting locked on OSX ... by eclipse not svn. suggests the problem is Eclipse.

It appears that the problem is that something called the file flags are set. File flags are different than file modes. ls -O shows the file flags as uchg, which means the user can't change the file:

The chflags command can be used to set the flags:

See How To Fix Stubborn Trash and Why it Won't Delete.

To see what files have the file flags set in a directory tree, run:

To fix all the files, run

The cause of the problem is probably natives/macosx/localfile.c

See Eclipse Bug 188874 Import from FileSystem damages the files' chflags flags

File attributes

Modes

Files have regular unix modes, use ls -l

Access Control Lists (ACLs)

Files have Access Control Lists (ACLs) ls -l shows a + in the modes column.

     Use ls -le for more info

The -e option to ls shows Access Control List info.

Extended Attribute Keys

Extended attribute keys and sizes - These are the Mac specific attributes that tell what app to open. ls -l has a @ in the first column. Use ls -@ to view:

Use GetFileInfo and @@SetFile

File Flags

Use ls -O and chflags

Backups

We've had several problems with the Apple Time Machine

• It takes 30 hours to restore an entire machine
  • See James Duncan Davidson's post Restoring from Time Machine, he suggests
    • Carbon Copy Cleaner - $10 shareware
    • Superduper
  • See Bob Tabor's post Time Capsule and Time Machine are SLOW
  • This could be because of the anti-virus?
• We've had to reformat the Time Machine at least once
• It can take a long time to fsck a backup partition on the Timemachine. During the fsck, it is not obvious that anything is happening.

Migration Assistant

The Wikipedia Migration Assistant page says:

• Tiger's Powerful Migration Assistant 2005 article

Target Disk Mode

• Wikipedia's Target Disk Mode page says that two Firewire macs may be connected and when the target machine is booted, the T key should be held down.
• How to use FireWire target disk mode
• I'm not sure if it is possible to do a full boot drive backup using target disk mode
• Use target disk mode to create a disk image backup - This allows you to create an image file of a machine, which might be a solution.

Command line

• Bombich.com - How to Create a Bootable Backup of Mac OS X (Cloning Mac OS X disks)

We ended up using Carbon Copy Cleaner, which is free to educational use.

When using Carbon Copy Cleaner, if the external drive is to be bootable, it must be formatted Mac OS (Journaled), see Formatting & Partitioning a Hard Drive in OS X - Tiger and Leopard

Spell Checking

It looks like aspell is the way to go.

aspell -c foo.txt was failing with Error: No word lists can be found for the language "en_US".

The fix was to download the en dictionary from ftp://ftp.gnu.org/gnu/aspell/dict/0index.html and then do (:source) tar -jxf ~/Downloads/aspell6-en-6.0-0.tar.bz2 cd aspell6-en-6.0-0/ ./configure make sudo -i

1. cd to the aspell6-en-6.0-0 directory

make install (:sourceend:)

Apple Repair at UC Berkeley

Apple laptops purchased as part of the departmental purchase have a three year warranty.

1. Get the serial number, which is inside the battery bay on a laptop, or try Apple (in the upper left) -> About this Mac -> More info
2. Go to https://selfsolve.apple.com/GetWarranty.do
3. If your machine is under warranty, then "Connect with an Apple Advisor" will be an option. This choice allows you to set up a telephone call back, which is much better than going to the store.

If you choose to have a box sent to you, then be aware that the box will be sent to you on the next business day, which means if you call on Friday, it will arrive on Monday. If you ship out on Monday, then the machine will arrive at Apple on Wednesday.

When you send in a machine, you will be asked for your password. There is a chance that your machine will be wiped as part of the repair process. If you do not want to give your password or possibly have your disk wiped, then open the case and remove the hard drive. Note that removing the hard drive can be very difficult for some machines and it requires a #6 Torx drive, which is very small.
