When Im working with large files photoshop eats up my memory and even if I clear the history and close the file I do not get my memory back, I have to quit photoshop and restart it?

Im using Mac snow leopard with latest updates.

Not a bug - Photoshop reuses memory constantly. There is no need to quit and restart unless you've been running a third party plugin that leaks memory.

This is less of a fragmentation issue and more of an application performance issue.

There is a significant performance benefit to allocating and re-using memory instead of de-allocating and re-allocating it each time we need it.

If you want more RAM available to other applications and the OS, lower the PS RAM % in Photoshop Preferences > Performance.

New in Photoshop CC (2015) - If you hold the Option (Mac)/Alt (Windows) key while selecting About Photoshop, or hold the Option (Mac)/Alt (Windows) key and select Edit>Purge>All – we flush (release) all RAM and scratch disc in use by Photoshop.
