Note of solving issue in MacOSX
Some painful experiences under macosx, for instance, lanuchpad resetting, incorrect user preference, etc.
Recently I finally found solutions for several issues in MacOSX, which bother me a lot since Yosemire upgrade. The tricky thing is that you can't find clear description of solution for some of them in Internet, Google, stackflow, etc. At least, those scattered information online just gives you simple hints, not real solution to settle down. After fixing them, my EI Capitan finally becomes clean and stable (clean launchpad and no trash after reboot) as before.
Reset Launch pad
My case:
As my Macbook pro is upgraded from Mountain Lion to EI capitan and I ever changed user name to llv23 with the same local home directory ~/llv22.
Problem:
When applied for traditional reset approach of launchpad, it could reset launchpad, but can't save the setting after adjustment, such as reordering, merging, etc.
Reason:
After detailed analysis, I found that key points for this issue:
- DB storage of launchpad changed to $TMPDIR../0/com.apple.dock.launchpad/db/, not previous ~/Library/Application\ Support/Dock/.
- After upgrade from previous system and change user name, owner name of DB storage and cache still keep the same as before. As EI caption introduced System integrity protection and previous item with incorrect owner name will mark as locked attribute. This leads to invalid write operation of reordering change events of launchpad into DB storage, as it has already been marked as locked.
So you have to change lock attribute for DB and cache folder, and follow the traditional approach.
Solution:
# After upgrade this db cache is locked, must unlock first of all
$ sudo chflags -R nouchg $TMPDIR/../0/com.apple.dock.launchpad/db/db
$ rm ~/Library/Application\ Support/Dock/*.db
$ rm $TMPDIR../0/com.apple.dock.launchpad/db/db*
$ defaults write com.apple.dock ResetLaunchPad -bool true; killall Dock
After resetting, you can clear see in $TMPDIR/../0/com.apple.dock.launchpad/db folder, db db-shm db-wal have been generated successfully. All of changes for launch pad could be saved, even after restarting system.

Package control of Sublime Text 2
Problem:
Always report certificate issue of sublimte text 2, after upgrade to EI capitan. Issue reported as follow from python:

Trash of MerpAD
Problem:
After restarting system, I can find MerpAD garbage in trash, after install certain upgrade of office on mac.
Reason:
Office enable error reporting, the recovered files folder will be re-generated after system reboot.
Solution:
1. Open application Office error reporting, the application is located in this folder /Library/Application Support/Microsoft/MERP2.0
$ cd /Library/Application\ Support/Microsoft/MERP2.0
$ open Microsoft\ Error\ Reporting.app/
2. Go in preferences
3. Uncheck enable office error reporting
