What computers are affected?

The up-to-date list of Macintosh computers models no longer supported by Apple is available from Apple Support.

Software for Vintage and Obsolete Computers

If you are using an old operating system or computer which is no longer supported by Apple, you might still find software products for your Mac here. In some cases, we even develop new or updated software products targeted to old systems.

Please use the following, alphabetically sorted list of applications to find the software product you may be looking for.

Note that these applications must not be used on up-to-date versions of macOS. Those operating systems were unknown at the time the software was developed, so technical conflicts could arise that might result in data loss. Most programs have an internal safety feature which prevents you from using them with incompatible operating systems.
