Switching from Windows to Mac? The ONLY 10 tips you need to know - Duration: 14:50. Macinhome Mac Consulting - Apple Certified Consultants 618,987 views. Like iPhoto, Photos can only load one library at a time and can only convert libraries to its format. You can import a library other than the default one you used with iPhoto into Photos.

(This how to from 2013 was written for iPhot0. However, this trick works just as well in Apple’s new Photos for OS X app.)

Family computers can be complicated. Sometimes, if a family is smart and manages their Mac wisely, each person in the household will have their own Mac login. However, that doesn’t always happen – and when it doesn’t, using personalized things such as iTunes and iPhoto libraries can become a concern.

Fortunately, just as we showed you how you can use multiple iTunes libraries on a single Mac login, the same trick can also be performed with iPhoto! Besides the shared/family computer scenario, this could also be used for keeping various projects separate. For instance, if you are a photographer, you could have one iPhoto library dedicated to client projects, and a separate library for all of your personal images.

Setting up and using multiple libraries could not be more simple. To do so, simply press and hold the Option (or Alt, if you are using a Windows keyboard) button while launching iPhoto, and you’ll be able to select between multiple libraries you might have – or even create a new one if you so desire!

We hope you find this as helpful as we did – personally, I prefer to keep my personal images separate from my professional ones, and this does the trick quite nicely! For more helpful tips, check out our full collection of tutorials by visiting our How-To category!

1) Should a library of 54,100 photos be 222GB in size? I have seen other references online that have half the photos and the library is 20% of the size, etc. Does this ratio seem accurate or is something else going on?

It will depend on the pixel size of the individual photos, but my library has roughly 50000 photos and a size of 249.8 GB. So the size of your library is normal. My library is working fine. If others are having a much smaller library for the same amount of photos, they may be storing their photos as highly compressed jpegs or in a low quality.

2) Is there any benefit to running the repair utility again now that I have a 'new' Mac? Or is the problem likely in the old library regardless of where it's stored?

Double-click it again to zoom in or display it on a grid.See other photos taken nearby: Click Show Nearby Photos.Zoom in or out: Click the zoom buttons. Sync google photos to mac.

I would only run a Repair, if photos cannot find some photos, albums vanish , or similar problems that indicate a library corruption. Never run a repair without making a backup before you run the repair. If a library is damaged, a repair can make the problem worse.

3) I plan on purchasing one of the de-duplicate utilities that exist as I know there are some older photos that are duplicates (and probably a number of HDR duplicates as well), and they should all be cleaned up.

You may try to use third-party applications to remove duplicates, but stay away from from any program that will modify the Photos Library directly and not just collect the duplicates in an album. The duplicate cleaners that modify the library can damage the library beyond repair. Apple is warning about duplicate cleaners:

These applications are save:

Power Photos - it can exact duplicates or photos with the same filename or capture time, and is generally a great companion to Photos as a second browser

4) What is the best course of action for managing a large Photos library? Would using Aperature (as opposed to Photos) help?

Aperture is great, but no longer sold. And Photos should be able to cope with even larger libraries than you are using now.

If you want to split your library, it will make it easier to backup the library and copy it to other drives, but make it harder to use your photos, because you would have to switch between libraries. You can only have one library open at a time and searching across libraries is not possible.

The slowness you are noticing may be caused by the small RAM. 4GB of RAM is not much for working with large media files. Can your iMac be upgraded to more RAM?
