Preview not scanning on Mountain Lion
First problem with Mountain Lion, Preview doesn't scan. Although Mountain Lion includes a significant upgrade to Preview, it seems that there are still bugs to iron out. Wireless scanning is finally enabled out of the box and no longer needs to be reenabled every time I reload Preview. The bug I have ran into is that I get the warning "The selected folder is not writable" when I hit "Scan" and the app refuses to proceed. Here is the fix if you have that problem:
1. Close Preview
2. In the Finder, choose "Go To Folder" under the "Go" menu
3. Paste:
~/Library/Containers/com.apple.Preview/Data/Library/Preferences
4. It will open the hidden folder. Delete the file "com.apple.Preview.plist"
That's it! Preview should now scan properly. The only other problem I've had with Mountain Lion is that the printing manager no longer auto-quits. Have you found a solution to that problem?
iMessages on the Mac
Apple just announced that we would be seeing the release of Mac OS 10.8 Mountain Lion this summer, barely 12 months after the release of 10.7 Lion. Most features seem to point to a continuation of the convergence of OS X and iOS. The upgrade will overall certainly be worth the cheap upgrade price Apple has adopted with the previous releases of OS X. Perhaps the feature I was the most excited about is the addition of iMessages. Although the concept is extremely simple, Apple is essentially bringing texting to Macs. Perhaps even more exciting, Apple went ahead and released a beta version for 10.7 Lion. It is certainly delivering on its promise; the implementation is flawless and it syncs amazingly well with iMessages on the iPhone and iPad. I was surprised that the background notification even disappeared on the iPhone when I switched app on the Mac and the iMessage became "read". The speed of synching is truly amazing, the notification disappeared as soon as I hit "Command-Tab" on the Mac. I do have negative comments about the app however. It is mostly design-wise; it feels like an app that came with Mac OS 10.2 Jaguar. The design is really 2002 and Apple needs to rework it. Rumours are also floating on the web that the icon is a ripoff of HipChat, but frankly, they shouldn't have bothered copying another app, the icon needs a redesign as well to make it worthy of Mountain Lion.
Here is a direct download link to the beta of Messages for Mac (OS X Lion 10.7.3 required).
