Version 10.10.4
Review by D.A.H. Trump

Photos + Runs great as usual… Apple Music needs consistency - So far so good. The app is simple, yet powerful and very intuitive. It makes the old iPhoto look old and clunky and it brings a bigger focus to photos than it’s predecesor, iPhoto. It loads faster too. I had the old iPhoto app and it loaded so slow I usually avoided opening it because it slowed down my computer. I have over 13,000 photos and videos now in the Cloud and the fact that it syncs on all devices is very convenient. Something I have been waiting for. This is just MY personal review. The rest of Yosemite runs great as usual. Despite the negative reviews, I like it. Only buggy thing to me is Apple Music. Don’t get me wrong, I love it and use it daily, and as a fan of music, there’s a good chance I’ll be a subscriber, but there’s problems, like in some places you can click “Add To My Music” and some places you can’t. It’s kind of inconsistent and I prefer the iTunes method to searching for music as opposed to the Apple Music way. e.g. for Apple Music It just looks like a bunch of categories thrown together. The “For You” section looks neat, but I don’t find myself using it often because it doesn’t really give me my taste. I could be favoriting 1000 smooth jazz and J-Pop songs and all the “For You” focuses on is Hip Hop and EDM… At least for me. Given Apple’s reputation, I have a feeling these will be straightened out in the future.

Version 10.10.4
Review by kwanyip

iPhoto Library unable to open - OK, it’s going to sound like I need to press option + click on the icon to open and to get the different option to select the library to open, etc. Nope. After a month of going back and forth with apple support, yesterday I received a call by the tech support rep that the engineers could not figure what was going on with the library and Photo not being able to talk to each other (or something like that.) After my laptop automatically updated the OS to Yosemite, it could not open the old iphoto library that contained 81 gigs of photos (collected, edited, fixed, etc.) for 10 years. Tried all the standard fixes, etc. over the course of a weekend: nope. Called support: nope. Took the laptop to apple store: nope. Call tech support: nope. Tech support talked to the engineers, got back to me with no solution, and that became a month of phone calls, emails, collection info, screenshares, etc. from my computer for them to see if they could do something or figure the problem: Nope. No solution. Just had the last call now with customer support. No solution. The issue was reported. They are really sad, and worried about this, so they offered me 100 dollars discount coupon to use at the Apple store next time when I need to buy my next imac/macbook/ipad... (ah, and they could purchase the old one too.) Please Apple, don’t laugh in my face.

Version 10.10.5
Review by TylerC101

Deletes a ton of routines and files - I upgraded from Snow Leopard so I could use one program I had an interest in, it was a huge mistake. Ignoring all the flaws in the new design the new OS deleted XCode, removed numerous installed items, deleted many old software I used to use. I guess I should have anticipated this, but I didn't and now I'm paying for it. I use this computer for work and Apple chose to make numerous programs I use not work instead of properly upgrading their OS. I'm livid, and I will be reverting to my previous installation once I finish my current project for work. I will not be using any apple computer with an OS beyond snow leopard again. Apple needs to stop improving on things that already work and start focusing on making the things they failed to produce well the first time work as were meant to work. Apple looks more and more like Microsoft every day.

Version 10.10.5
Review by MandyT1982

Are You People Completely Insane? - I have never used an operating system as slow as this. What is wrong with Apple? I am upgrading the OS on my 27" mid-2011 iMac. Is Yosemite incompatable with this iMac or does everybody have to deal with this? I agree, "Every bit as powerful as it looks" with a photograph of a big rock behind it. I swear, I am tired of this crap, and am erasing the partition with Yosemite and going back. I will never upgrade again to an Apple OS that runs slower than what I am currently using. I will sit on my current OS until every application is no longer supported, and then switch to a PC. All of my friend's computers run like lightning compared to Apple's 3 most recent OS versions that I have tried. So disappointed!

Version 10.10.5
Review by Max28473

What’s going on Apple? - I waited to give this review on the new update to make sure its not just me not understanding it or maybe its just the settings that were changed. The new operating system drains my battery faster, gltiches alot and has slowed down my system. Now I get that updates with operating systems can be more demanding on older systems but this seems like its kiling my MacBook Pro. Apple used to be great at innovation and making a functional product but now it seems they're more worried about astectics then performace. I love my MacBook because it used to be a solid system but after this last update Apple really needs to improve the operating system. Granted this update was free, but that doesnt mean that they should release a product that seems rushed. I’ll probably try to revert to the older operating system and keep that until they fix some of the issues with Yosemite.

Review by SusanG249

Everything’s good but Photos - The OS works fine. But I hate it that Photos is now part of the package. It should be separate if only so those of us who liked iPhoto (and used it a ton) can complain about Photos and make suggestions for improvement. Please don’t combine more programs with the OS! And please give people more control over what automatically happens to their stuff when updating. (Photos migrated my photos already, seriously?!) I’m sticking with iPhoto until I can make Photos function more like iPhoto. Thanks for making a great OS that includes a program that promises to make my life more complicated.

Review by samothebigho

Corrupted my hard drive! DO NOT DO THIS! - I tried to do this Yosemite whenever it came out- had nothing but probs since. Pages freezing and taking forever to load. BUT the worst part is, it eventually dorrupted my hard drive (according to Mac repair). So I lost everything and had to get a new hard drive. I kept my old one and currently having someone get the info off of it, IF they can. 6 years worth of picutes (8,000+) and over 4,000+ songs. GONE. Yeah yeah- i should have had it backed up.. But still, this shouldn’t have happened!
