This is the time-line I update:
MacBook: OS 10.10 > MC 21 > MC 22 Crash with library change
Mac Mini: OS 10.10 > MC 21 > OS 10.11 > MC 22 Work Fine
On my MacBook, I just delete all files at
1. '~/Library/Application Support/J River'
2. MC22.app under /Application
3. All library files at other folders(some is in ~/Documents)
Then I reinstall the MC 22. I create a fresh library, and load the library from my Mac Mini (3 libraries: default, new, LAN). Works fine.
But after I restore 'settings' (I only checked 'settings' without library) use your method. The crash becomes...
Does the backup files only work correctly on the same computer? I use backup zip from Mac Mini and restore my MacBook. The problems continues.
However I have many custom views, shortcuts, and etc. You know that configuration will cost so mush time...
On the crash:
I've seen this happen before with MC21. I've probably seen it at least 20 or 30 times; maybe more. But it's occasional for me. It doesn't happen every time. Like you said, after the crash, when I restart MC, the library I wanted to switch to has been selected. I don't switch libraries all that often. Really, there are VERY FEW good reasons to even have separate libraries.
On uninstalling: I'm no expert on this. Glynor knows more. The developers know more. But I'm pretty sure that MC on the Mac consists of just a few pieces: The actual app files which are in Applications. The Library files, which can be anywhere, though the default is under ~/Library/Application Support/JRiver . Finally, a number of configuration files which are under that same directory I just listed.
I think if you delete all 3 of these, you'll have a very clean uninstall.
I'm running OS X 10.9.5 and have had infrequent crashes of this type. What version of OS X are you running?
