"Basically the Users folder (Guest, Shared, and my admin), which has the usual Desktop, Documents, Library, etc. So I can still manually retrieve things like my iTunes library, documents, some photos (although I've been having trouble importing the old library into Photos)."
Here's what I'd suggest:
You'll need an EXTERNAL DRIVE large enough to "hold that folder."
Then, do this:
- Copy the folder to the external drive
- Select the icon (icon only) for the ENTIRE external drive by clicking on it ONE time
- Now type "command-i" (eye) to bring up the get info box
- Down at the bottom of get info, there is a lock icon.
- Click the lock and enter your password
- Now, put a checkmark in "ignore ownership for this volume" (sharing and permissions)
- Close get info
WHY you did this:
Now you can copy ANYTHING from your "old" administrative account into the new one, WITHOUT experiencing any "permissions problems".
WHAT TO DO NEXT:
You can "manually copy" stuff from the external drive into your -NEW- home folder (or other locations).
I SUGGEST YOU KEEP HANDWRITTEN NOTES so that you don't lose track of "where you are".
Do you have much in your NEW iTunes?
If not, you -could- just copy the OLD iTunes music folder into your new "Music" folder (replacing the new iTunes Music folder)
Another way might be to tell iTunes to import everything in the old folder.
I'm hardly an "iTunes expert" -- don't use it much.
For Photos -- again, how much is in the "new" "Photos library" vis-a-vis the original one?
If most of your stuff was "in the old one", I'd move the new Photos library OUT OF the "Pictures" folder -- to the desktop might work.
Then, I'd "drag and drop" the OLD Photos folder from the external drive to your NEW "Pictures" folder.
Then, hold down the option key when you open Photos and pick the "replaced" library (yes, I realize it's "in the same place as the other one was" -- do it anyway).
Then -- work on "re-importing" the (formerly new) Photos library on the desktop back into the old one. (sigh, this is confusing!)
For document files, you ought to just be able to "manually copy" them wherever you want.
This might work for some applications, as well.
One last thing:
IF you had had a backup, you wouldn't be in this situation.
I suggest you get an external drive and try either CarbonCopyCloner or SuperDuper.
Both are FREE to download and try for 30 days.
SuperDuper will keep doing "a full clone" forever without registering.
Don't let this happen again!
