MacBook Pro 2010 Intermitent Shutdown Issue

My MacBook 2010 was having an intermittent shutdown issue.  It would stay on for 30 minutes, then just shut off.  Nothing would be stored in the console logs which indicated anything was wrong with any programs running.

I opened up the machine and when I got to the right corner near the trackpad, it kind of popped open.  The battery had expanded on the right side (near the connector) and cracked the plastic case that hold the battery contents and was pushing against both the trackpad and the case.  The battery was "dead" for quite some time which I never did anything about.  Seeing this, I removed the battery, and the intermittent shutdown's have thankfully ceased.

End of Story.

Disabling Default MacOS Mavericks "All My Files" Finder View

To get rid of that annoying "All My Files" default view in Finder, update the drop-down list in: 'Finder / Preferences / General / New Finder windows show' to something else.  I have my home directory now.  Saves at least a few seconds each time I need Finder.  (See images below)

Datahand RIP

RIP Datahand.

I would *love* to get another Datahand, or some how fix the two broken ones that I have (I've taken them to fix them many times -- seems like a logic board issue this time).  I have tried to contact Datahand by voice (mailbox full), and by email (mailbox full) and now it appears the website is down.  If anyone has any info, or a broken Datahand that I could buy some parts from, please let me know.

Natively Compressing Files on a Mac to Save Space

Since 10.6 (Snow Leopard) native file compression has been built into HFS+ (the MacOS Extended filesystem).  

The feature is hidden away in a command line utility called ditto (you can check the man pages for the command via "man ditto") which is a file/directory copying program.  

Apple hasn't recommended it for the following reasons but if you don't use computers prior to 10.6, you'll be fine.


     --hfsCompression
                   When copying files or extracting content from an archive,
                   if the destination is an HFS+ volume that supports compres-
                   sion, all the content will be compressed if appropriate.
                   This is only supported on Mac OS X 10.6 or later, and is
                   only intended to be used in installation and backup scenar-
                   ios that involve system files. Since files using HFS+ com-
                   pression are not readable on versions of Mac OS X earlier
                   than 10.6, this flag should not be used when dealing with
                   non-system files or other user-generated content that will
                   be used on a version of Mac OS X earlier than 10.6.



In it's simplist form, use it this way to compress a directory:

ditto  --hfsCompression sourceDirectory destinationDirectory

In my case I had a lot of applications that I didn't want to delete but that I might not ever use i.e.

sudo mv /Applications/Xbench.app /Applications/Xbench.app.old
sudo ditto  --hfsCompression /Applications/Xbench.app.old /Applications/Xbench.app
sudo rm -rf /Applications/Xbench.app.old

You can check the compression status with a utility like hfsdebug or fileXray or do a df -h before and after a compression to see that the disk storage used by the command is usually much less than without.

Alfred Applescript Extension Tutorial

This extension for Alfred which will lookup your lastpass url names and launch them in a new tab in safari.  

In this example, we'll lookup Blogger with Alfred and


it will find this entry and run it in safari.



Things you'll need. 

  1. a copy of your last pass CSV file place into your home directory named lastpass.csv.  Get this by going to the Advanced screen and clicking export
  2. Alfred with PowerPack 
Note: If you want to be more secure, edit this lastpass.csv and remove all your passwords 



Go to the Extensions button
Click AppleScript

Name AppleScript

Add code and metadata to alfred and save.

Run it by bringing up Alfred as follows.  Safari will kick off with the matched entry.

Reminder: Make sure you have an exported copy of your last data into your home directory named "lastpass.csv".  I know this is insecure.  I tried to remove the passwords programatically but applescript keeps giving me errors when I try and open a file for write ( Network file permission error., errorNumber: -5000).

Note: I'd rather have the alfred team properly integrate this feature the app.  I want it to search ALL elements and show the list of items that matched, but I can't see a way to make an alfred extension do that as written.

Code to copy:

on write_to_file(this_data, target_file, append_data) -- (string, file path as string, boolean)
try
set the target_file to the target_file as text
set the open_target_file to ¬
open for access file target_file with write permission
if append_data is false then ¬
set eof of the open_target_file to 0
write this_data to the open_target_file starting at eof
close access the open_target_file
return true
on error errorMessage number errorNumber
log ("errorMessage: " & errorMessage & ", errorNumber: " & errorNumber)
try
close access file target_file
end try
return false
end try
end write_to_file
(* Assumes that the CSV text adheres to the convention:
   Records are delimited by LFs or CRLFs (but CRs are also allowed here).
   The last record in the text may or may not be followed by an LF or CRLF (or CR).
   Fields in the same record are separated by commas (unless specified differently by parameter).
   The last field in a record must not be followed by a comma.
   Trailing or leading spaces in unquoted fields are not ignored (unless so specified by parameter).
   Fields containing quoted text are quoted in their entirety, any space outside them being ignored.
   Fields enclosed in double-quotes are to be taken verbatim, except for any included double-quote pairs, which are to be translated as double-quote characters.
       
   No other variations are currently supported. *)

Windows 7 Printing to Mountain Lion Problem Resolved

I spent about 2 days trying to get my Windows 7 Machine to print on a Mountain Lion Mac.  I did the usual things like 
  1. turning on the printer sharing in the System Preferences
  2. turning off the firewalls, 
  3. verifying connectivity, (tracert, ping, nslookup) 
  4. using the windows 7 printer setup and trying 
    1. browsing for the printer (nothing would show)
    2. typing the IP address
    3. typing the host name
    4. typing the full name i.e. \\host\printer
but no matter what I tried, the windows 7 machine would not see the printer.
In the end, I realized that I needed to 
  1. install Bonjour (apple's "zero configuration" networking utility) on the Windows 7 machine 
  2. run the Bonjour printer wizard and connect it to the mac's shared printer,
  3. That's it! Printer installed and working.
Hope that saves someone else some grief!!
