After installing OSX El Capitan ( OSX 10.11 ), I ran into several problems:
- I was unable to modity system files
- Problem with Java based apps
- Problem with kernel extensions
- Menumeters no longer works
Here are some workarounds.
Unable to modity system files
The problem that I could not make some of my usual edits: remove the -nobody- restriction in /usr/libexec/locate.updatedb.
The error in the syslog: sandboxd: System Policy: deny file-write-data
The problem here is that the sandbox restrictions have become much more strict now.
My quick solution: copy locate.updatedb to another location, edit, and run from there.
Problem with Java based apps
Several Java based apps ( minecraft, and Arduino IDE ) fail to run for other users(my kids) than the one who installed them on my laptop.
The problem i found: something needs write access to the launching binary. Why? - i don not yet know.
Solution: copy the app for each user to his home directory's
Problem with kernel extensions
In OSX 10.11 code signing became mandatory. Now i have a problem loading the CH340 driver ( used for cheap arduino clones )
sudo nvram boot-args="kext-dev-mode=1 rootless=0"
csrutil enable –-without kext
Menumeters no longer works
Solution: update by yujitach
