My MacBook Pro, running Snow Leopard i.e. Mac OS 10.6.8, often hangs during shutdown. If I start it up, do almost nothing, then shut down it is ok. But otherwise, if I do something significant, like run Adobe Premiere, it hangs on shutdown. The only way out is to “Button It” i.e. press and hold the Power Button to force a power-off. This leaves the file system slightly damaged, as reported by [Boot Camp > Windows] (not sure if I have MacDrive running or not), if I happen to run that immediately afterwards.
On booting again to Mac OS, the OS appears to mend the file system and recover lost files, which appear in a [Recovered] folder of [Trash]. Typically these are files I (directly or indirectly via an application) most recently created prior to shutdown, for example Adobe project-saves and cache file saves.
This is a nuisance, and (naively at least) raises concerns of some more significant kind of damage occurring some day…
Web-search suggested maybe Kapersky Anti-Virus 2011 (for Mac) might be responsible. My experience indeed confirmed that – once I removed Kaspersky (for Mac), the Mac OS shutdown behaved normally once again.
{BUT, as recorded in my next post, re Adobe, could the apparent Kaspersky-hang be the result of an Adobe failure-to-terminate process?}
Kaspersky removal:
- Since my copy of Kaspersky (for Mac) was installed as part of Parallels Desktop 8, it did not come with its own installer/uninstaller package. Instead I had to run Parallels Desktop (no need for any of the VMs to be running, just the “shell”), then use menu option: [Parallels Desktop > File > Uninstall Antivirus for Mac…].
- Tip: on doing that, nothing seemed to happen for quite a while, so maybe worth leaving it for say 15 minutes to see if a confirmation “Removal succeeded” message pops up. Or if that doesn’t work, try updating Parallels Desktop and trying again (that is what I ended up having to do).
