Updating from tiger to leopard
Its System Requirements on the low end are identical to its predecessor Sierra although some new features may require newer hardware. Also, unlike Sierra, your Mac must be running a mimimum of Mountain Lion.
The one exception was a version of Mac OS X Tiger Server which was released with a number of problems that went unresolved for a week or so.
The Postfix mail system was broken, some web server functions were disabled, along with a few other Server problems which Apple did not correct for nearly a week. The next full update brought the Server version back to normal.
With such a large and important update coming for Leopard users, preparation is important. Give yourself time to complete the backup, check out your system, without the process interfering with your work. Six hours after we published this article, Apple released Leopard 10.5.2, weighing in at a whopping 180 megs for the individual update, and over 300 megs for the Combo update.
Also available is a Leopard-only Graphic update, and some recent Security Updates have been integrated into a single installer.
The steps below should help you avoid the most common mistakes in updating and avoid the most common contributing factors.
On September 25, 2017 Apple released 10.13 High Sierra.Most of the updates or upgrades (pretty much the same thing for most Mac users) are mostly painless improvements to the latest OS X. The subsequent reinstallation of the update went fine. This one will be Mac OS X 10.5.2 and many developers working on beta copies say it will be the largest, most expansive minor version update ever for OS X.Generally speaking, my routine for handling OS X updates, Security Updates, and so on, has been the same through the years.Every couple of months Apple releases a new version of Mac OS X. Since Jaguar’s arrival a little over five years ago, I’ve experienced one bad upgrade for each new release of OS X. In each case my Mac was grounded and would not run properly.As with Jaguar, Panther, and Tiger, the updates come five or six times a year. In each case I had just completed a cloned backup to another hard drive, so recovery was simple and quick, and, with one exception, only a minor inconvenience. Apple is preparing Mac users for another Leopard update, the second since the initial release last year.Many Mac users have problems with updates, though the process is as automated and straightforward as possible.
