Hey everyone, quick question:

I've been using Time Machine to keep backups of my 10.5.6 install on my MacBook and I would really like to upgrade to 10.6, but I always prefer to do a fresh install. Can I expect Snow Leopard to read / restore / transfer from the 10.5 backup? Are they compatible? Will I have to reinstall all my apps?

    *Will I have to reinstall all my apps?*

    You might want to remove any 3rd party applications before upgrading to Snow Leopard as they may not be compatible. You will not have to reinstall the Mac OS X applications.

    Hi nugx

    There's no reason to go thru all that rigamarole, besides fewer folks have had issues upgrading than the one's trying to migrating back.

    As far as I'm concerned upgrading the OS has always been the best way to go, besides you have Time Machine and/or a bootable clone to fall back on right?

    After the upgrade your current Time Machine backups will required some time for a deep transversal, but should then resumed without a hitch.

    10.5.6 the current version of Leopard is 10.5.8 ???

    How-To: Upgrade To Snow Leopard — The Right Way

    Personally, I'm not at all impressed by Cult of Mac's idea of "the right way" to upgrade to Snow Leopard or the reasoning behind it.

    First off, the author(s) explain that their experiences upgrading from Tiger to Leopard leaves them "a bit wary" of Apple's provided method. OK, I know that some Tiger to Leopard upgrade experiences didn't go so well (because mine was one of them!), but the Snow Leopard installer is quite a bit different from (& a substantial improvement compared to) the installers provided for the previous OS X versions. It does not "install Snow Leopard right on top of your existing Leopard install," as the authors claim. Had they tried it & checked the installer log, they would have known this.

    Next, they say that they are such big fans of the "start from scratch" option that they "actually do it every six-months, wether {sic} or not there is an OS upgrade to be performed." Later they talk about how much time it will save if "you’ve removed most of the useless garbage from your drive first." Hello? If there is "useless garbage" slowing down their Macs (or yours), then there is something wrong that needs fixing, & periodically starting from scratch is not the best way to do it, or one that will save you time in the long run.

    Then there is the recommendation of using OmniDiskSweeper to "sweep" that garbage from your drive. It is a fine application, but a) there is no reason to delete caches, unused print drivers, etc. from the drive because the Snow Leopard installer does that anyway, b) if you just go by size to decide what needs to be deleted, you will probably delete stuff you shouldn't, c) they recommend cloning the drive after you do this (meaning no backup of that stuff you shouldn't have deleted), & d) this is unlikely to save any significant amount of time during the Snow Leopard installation but it will take time to go through all those files looking for stuff to delete.

    I could go on, mentioning the "smart" features of the Snow Leopard installer that you will miss out on by doing a clean install, but basically it boils down to what den.thed has already mentioned: most users are more likely to have upgrade problems if they try a "clean" install & manually do what the installer will automatically do for them than if they just follow Apple's instructions & click the button.

    Note: the one thing I think the Cult got right is the desirability of cloning your existing startup volume before upgrading. A good Time Machine backup will provide the same kind of ability to regress to a prior state if necessary, but a clone is a much faster & easier way to do this, & easier to test.

    [Here is a good read for you|]. I also would be strongly inclined to have a bootable clone of my internal on an external drive to provide an ultimate fail-safe mechanism.

    If you want a squeaky-clean install, then use the same user name, password, etc., as on your old system when you install; drag and drop your data from the clone; reinstall your apps by hand, and redo your settings. If you have many apps, or some your don't want to reinstall, then you could take a shortcut; go ahead and restore them from your clone.

    as others have noted there is no great reason to do this unless you plan on skipping some things when migrating but yes, this will work. after doing an erase and install you can import your data from the TM backup during the original postinstall setup. or you can do it later using Migration Assistant, which is located in /Applications/Utilities.

    Hi nugx

    Personally I look your idea of fresh install, I assume you mean an Erase & Install, as a pure waste of time carried over from Windows.

    The only time I think an Erase & Install should even be considered is if you have extremely serious problems with a Mac and you have proven that is not hardware and you have attempted all software solution. Then I think you can consider it.

    See my earlier post. Yes, I attempted to deal with the subject matter you indicated interest in.
