how do I re-download iphoto onto computer?

What system are you running and what version of iPhoto did you have? Did your computer come with Lion or Mt. Lion preinstalled? If so go to the App Store, log in with the Apple ID that was used to purchase or register your Mac, click on Purchases

and download iPhoto.

If your Mac came with Snow Leopard or earlier preinstalled then use the disks that came with your computer to reinstall iPhoto.

OT

Reinstall from the original source - the restore disks that came with yoru comuter - or the purchased iLife DVD - or the App store

How did you load it on originally?

If you bought it from the Mac App Store log in using the same Apple ID you used when you bought it. It will show up in your purchases list. Install it from there.

If you bought it in some other way post back.

Looks like a 3 way photo finish. 🙂

Seems you won by a hair 😉

Or a nose.

Or you "hopped" out to the lead 😝

Ribbit, ribbit, ribbit.

We certainly have way too much free time on our hands. 🙂

Sorry for starting an old trend... But this is the only Apple support on the subject that I can find.

So my Brother in law is not able to get past the "Open Splash" for iPhone on his Mac 10.10.4

For some reason, while he can't get past the splash screen, when he try to uploads the iPhoto library comes up.

I had planed to delete it and reinstall iphone. It says "can't delete photo because Mac Os needs it"

Any help deleting and re-installing would be helpful.

I just realized, "iPhoto" is working, "Photos" is not-- problem temporally solved.
