Urgent Question: OS X 10.6.3 vs 10.6

That should work fine.

Also note the web site links to update 10.6.8 for Apple mac app store access

and the later link to El Capitan (reverse order) in my reply to someone else here:

How do update the imac operating system?

Good luck & happy computing! 🙂

Installing or updating Snow Leopard:

http://manuals.info.apple.com/en_US/Snow_Leopard_Installation_Instructions.pdf

The Combo 10.6.8 updater can be downloaded from here:

https://support.apple.com/kb/DL1399?viewlocale=en_US&locale=en_US

As stated, this would be a retail version Snow Leopard 10.6.3 DVD

and then there is an update-download to gain 10.6.8 status. ~ Plus

at least two/three other updates beyond Combo/final to get to the

Mac App access level. You may see content in App Store -- but, if

10.6.8 isn't fully updated, the content will not download or work.

Note the Combo 10.6.8 is required before the last (top-most) is tried.

Because I've not upgraded an older Mac to Snow Leopard, lately

10.6.8 and the status to gain access to Mac App Store; note

there are few (four?) update bits that may not all be required:

The first one on this list, is likely the last one to install; it's newest:

Mac App Store Update for OS X Snow Leopard - Apple Support

Yes, this disk will work, although the latest Snow Leopard version is 10.6.8. To get 10.6.8 for free, choose Software Update from the  (apple) menu. The first version that has the App Store is 10.6.6. However, if you want to upgrade to High Sierra (The latest macOS right now), you must have a computer from 2009 or newer. To check your computer model, choose the  (apple) menu and choose About This Mac.

There also was a 'family pack' version of Snow Leopard 10.6.3, for up to five Apple computers;

saw one the other day in the box for $15. Thought to maybe get that if they had a local phone#.

But the CL ad didn't have contact info; or I'd have considered.

Due to my MacBook1.1 Early-2006 model could use an upgrade from 10.5.8 Leopard. Already

has full RAM upgrade, larger fast RPM (7200) HDD + for first build 1.83GHz coreduo, does OK.

More than 10x faster than my Mid-2005 iBook G4 1.33GHz w/ 1.5GB RAM & 37GB HDD with

both builds running 10.5.8. The iBook G4 has been reverted to its original Tiger 10.4(.11).

Sometimes the updates for an older system may not appear when its installed & running the

Software Update. For the older models I've saved those updates on local backup media.

And there are a few still-working links to Apple Support for crucial ones; but not all.

Good luck & happy computing! 🙂

10.6 was the first Snow Leopard on a DVD installer. 10.6.3 is the last DVD as all other updates are internet downloads.
