Q: When I restarted my mac, it deleted some of my editing softwares. How do I recover them?

Have you tried to restart in safe mode (shift key held on startup) until or if you can

get a window to login; then you may be able to use the computer to troubleshoot.

• Try safe mode if your Mac doesn't finish starting up - Apple Support

There may be damages to your computers hard drive, so some files or user account

could fail to appear correctly; depending on age and wear, a hard drive failure may

be expected at some point in the life of a computer. They can be replaced; but you

should have a backup of your running computer content -and- your files, outside of

the computer in externally enclosed hard drive. Also, Time Machine backups, as well.

•About macOS Recovery - Apple Support

Depending on the macOS (or OS X) version running on the computer, and its vintage

you may be able to start using instruction in OS X Recovery, to access Disk Utility

and other options from a menu that would load from that startup method.

If your computer has a BootCamp partition, or a virtual PC machine running, that can

add another layer of troubleshooting. ~ Since I don't know what your configuration of

hardware + software is, there's not a lot of specific information to give in that matter.

About passwords; if you have FileVault or encrypted partitions, or files, or if you

have a Firmware Password (lock) on your user account, those are different than

if you simply had a regular Admin account or standard account password issue.

And if you upgraded to a new macOS Sierra or other new to your Mac system, the

applications you had been using may not be supported or you may not have set up

the upgrade properly. Hard to say what you had been doing. OR what exact model

Mac you have there and what macOS X was involved before an update or upgrade.

In any event...

Good luck!
