new GM build? You mean the second GM build?
I haven't upgraded yet, but I heard that you can just download a new version from Mac App Store then upgrade it like from Preview -> GM, this can be done without wipe.
Second GM build came out today. Cannot be upgraded from Mac App Store.
This is bad advice.... 10.9.1 will be an update from the released version of Mavericks. It may not include the changes between the 2 GM versions.My advice:
If the "first" GM is working for you (and by "working", I mean working well enough, even if there's a minor glitch or two), don't waste time trying to get the second GM installed.
Instead, wait for the release of 10.9.1 update.
Install it, and it should bring you completely up-to-date...
This leads to an important question. Do you keep backups? If not, what will you do if/when your hard drive fails?Please help! How to install new GM build without wipe? I don't want to lose all my data but I can't software update to the new GM build. Please help!
I simply re-downloaded GM2 from AppStore and installed it on top of GM1. This worked without any issues.
How did you install GM2 over GM1? What are the steps?
