If you're not sure, then Don't! I upgraded from SnowLeopard I'm very Pleased with most everything about this OS! YES, the download is worth every penny!
I Hit ComMand-R.. Thank You apple! Reply Penguirl Oct 15 I still miss Rosetta, and the drab Finder sidebar is atrocious I find it harder to spot what I'm looking for than SL's sidebar but overall it's a lot better than I expected.
One thing I sorely miss, besides Rosetta, is the zero-out option in Disk Utility. With this option gone how are we supposed to write out bad sectors now? Reply Brooklyn-Al Sep 15 Why the file size difference? The App Store experience was not good as far as downloading goes, the download quit several times and an alert window popped up that gave an option to "retry".
It took the better part of a day to get this beast downloaded yes, I have broadband. As for the OS itself, I'm not so crazy about it. More bells and whistles, seems to me. Boot from another partition or drive, other than the one being upgraded. This ensure the partition to be updated is completely accessible and no files are open or in use.
In this day and age of inexpensive supersize hard drives, there's no reason not to have an extra partition to boot from for situations like this. It doesn't take much space. A bare bones install of Mountain Lion will fit on a 10 GB partition. If unable to boot from another partition or drive i. Go have some coffee while the upgrade is in progress, really you don't need to be working at the same time, those 15 minutes are small compared to the time you will waste if the install goes bad.
I run the Combo updater, even if I'm just upgrading from one point release to another. For newbies, Apple releases OS updates in two forms, 1 a smaller update that updates from the immediate prior release, like if you have For example the Why run the combo, even if just upgrading from the previous point release?
There have been times when Apple has forgotten files in the point upgrade, and the point upgrade is based on just covering the delta between the two points releases.
I do not have any proof of that, this is a personal opinion, I could be wrong, but in my experience I have had good results always using the combo. Besides if you read any of the Mac publications and tech pundits, nearly all of them recommend using the combo as well. If you have multiple Macs, or work in a multi Mac shop, it's also a lot simpler to keep one combo updater on hand, than multiple point updaters.
Hopefully, if you follow these steps it will minimize the possibility of those spurious, hard to pin down, system hick ups that are often reported here. Lastly, laptop users with smaller drives that feel they can't afford to set aside 10 GB for a boot partition, invest in an external drive, it's well worth it.
If you have a Time Machine drive, you can even partition off 10GB on that. Good Luck! Every time I try to use it to update OSX it grinds slowly away for a short while and then gives up the ghost and declares a fault. I suspect that the Software Updater cannot handle the load on it.
I find it is far faster to download updaters for OSX directly from the Apple download site. We also use third-party cookies that help us analyze and understand how you use this website. These cookies will be stored in your browser only with your consent.
