Accidently I deleted my Reading List in Safari which contained a lot of necessary information I collected for year...Is there any way to restore it if I doesn't have iCloud?
iCloud or possibly from a recent Time Machine backup.
Tried "Undo......" from Safari "Edit" menu?
No, I can't undo, because a lot of actions were produced before I noticed the problem
I don't have iCloud because of old verson of OS
Sorry, but you may be out of luck.
