System: Mid-2014 15" Macbook Pro Retina
HDD: 500GB
Memory: 16GB
CPU: 2.5GHz i7

Problems:
1. Since upgrading the OS, the system gets unusually warm. It is doing it now and I don't have much going on except Safari with two tabs.
2. Photos seems to work, but I don't really understand what is going on with the libraries. In Finder is says that I have a ~245GB Photos library and a ~250GB Aperture library. How can that be with only a 500GB SSD in the system?
3. Finder shows ~140TB available no matter what I have selected. I have a NAS, Dropbox, etc., but none of them have that much space.
4. Although totally unrelated to my MBP, the conversion/migration of the Aperture library on one of my iMacs hung up at 68% the first time and 55% the second time. It worked the first time on my MBP.

I am hoping all this is a result of user error; I would appreciate any feedback from the community.

My concern is that, after updating to Yosemite 10.10.3, Mail now has a delayed "jump" when I shift from one email to the next. I've not noticed that in other apps, but it is a bit disconcerting. Hopefully, it'll be fixed in 10.10.4, if not before.

Re: item 2 - Although Finder displays those two libraries as each being around 250GB, what's actually happening is that OS X is using multiple "hard links" to save space - one copy of the image file on the SSD, with both Photos and Aperture linking to the same file. https://support.apple.com/en-us/HT204476

If you delete one of those libraries, you'll see a relatively small change in the amount of available disk space. As long as a file has two or more hard links, it can't be deleted from the drive - a delete just removes the link (in your case, deleting the Aperture library just deletes Aperture's link to the image file).

Thanks for that information. Now if I can just get Photos to work on the iMac. It worked fine on my Macbook Pro. I haven't tried it on my newer iMac yet.
