Upgrading to Mavericks - painless?

[NickFitz]

Did it last week, though I had about 50GB free. No problems at all.

Is it a case of download, install, everything still works? I seem to only have 10Gb of space on the disk, is this an issue (I have no idea where the other 100Gb went since I use it for development work only).

10GB almost certainly won't be enough. The download itself is something like 4GB. A couple of useful utilities for finding where your disk space has gone:

• GrandPerspective Hmm - hasn't been updated since 2012, but a nice graphical interface which displays filenames and sizes via mouseover
• OmnDiskSweeper a much simpler interface but this is the one that found me an unexpected 100 GB I could get rid of

Both free. Tapping "free disk space" into App Store brings up a ton of free and cheap solutions, but I haven't tried any of these

By default the Mavericks Update download will delete itself after running. It won't self-delete if you move it out of /Applications before letting it do its stuff. You do that move by quitting once it says the download is complete and is asking for confirmation to proceed with the update.

fairly painless, a few small (but important) applications needed to be upgraded which was an unexpected cost..

Then I found this site - slightly late for me, but can help to check your software

As said above, avoid the beta Yosemite - it is not ready for a non test machine - glad I only did it on a clone drive!

I had to upgrade my Crossover app for running Enterprise Architect but that was about it.

I upgraded to Mavericks when it came out and haven't had any problems apart from my Canon printer stopped working over WiFi. I got an updated driver from the Canon website a few days later and it's been working fine since.

Yes, don't risk Yosemite though, I did and I'm paying the price.....
