Pros

includes some features original in linux, multiple desktops, thanks for not removing

Cons

trading in "save as" FOR duplicate or export?! this is garbage to have to work around to save a document where I want it.

Summary

whoever makes these decisions needs to be evaluated or forced to use design standards based on use data, not how ever the bad decision to remove "save as" was made.

Pros

Easy to intall, free download

Cons

Dark colors, finder is gone, system lag

Summary

I dowloaded this from the apple store, and at first I was interested, and it was
free. After using it for some time, I discovered that it was a mistake! The thing
I hate the most is the system lag- applications take forever to start, and I don,t like
the new colors. If there was any way to go back to snow leopard, I would!

Pros

More money for software developers

Cons

I moved over from the PC world in 2004, and it was the best thing I ever did to enhance my efficiency and enjoyment when using the computer (science-related work).

I was delighted with the OS 10.6 (Snow Leopard) although I could think of some really helpful improvements, but Apple is not listening much, if at all.

I upgraded to Lion, then Mt. Lion, Mavericks and Yosemite on my MacBook Air (MBA) which I mostly use when on the road but it is a good test unit while leaving my main iMac (i7 with 16GB RAM) untainted. I really believe Apple is blowing it badly with upgrades averaging once a year. This causes major stress to users WHEN it does not equate with improved efficiency, ease, enjoyment and security.

Reading these reviews confirms what I have found. Just losing the Finder sidebar of "Today, Yesterday, Past Week" is a major loss. Spending time to find work arounds is absurd. Apple, listen to your customers.

Summary

We are at a time in our life where simplicity is being replaced with pseudo-improvements. When it works make sure you check out your new "tweaks" before upsetting the APPLEcart. You have succeeded in taking a former Windows user to a devout Apple customer e.g., 2 MacBook Pros, 2 MBA's, 2 iMacs, an iPad, 2 iPhones, Time Capsule, equates with a huge expenditure. Apple, don't bite the hand that feeds you.

Pros

None. I've only had problems with my computer since installing this update. Maybe it was a pro for Apple to release something for FREE and have all the users do the troubleshooting for them. The obviously did not do extensive testing or troubleshooting beforehand.

Cons

FaceTime stopped working immediately after update. I am also no longer able to connect my iPhone to iTunes and sync files and settings. It's really annoying to pay $2K for a computer and then install an automatic update which is supposed to "increase security" but which actually makes basic applications that I use on a daily basis stop working properly. BAD JOB APPLE.

Summary

If you're someone who reads reviews before installing updates (I finally got sick of the stupid reminder window that wouldn't go away), DO NOT INSTALL THIS UPDATE. You will definitely regret it. Too much of a headache, not worth any potential benefit.

Pros

We were so busy trying to find out how to make it work, we never had the time to discover if there were any pros.

Cons

Too numerous to mention. Peripherals, such as printers, all of a sudden decided that they should became invisible to the computer. Documents prepared earlier could not be read. Mail programs refused to work or if they did, disgorged emails counted in the thousands from years earlier which we had thought had been deleted reappeared as if by magic.

Summary

My wife was ready to throw her mini out the window when I turned to Apple's excellent Time Machine backup program. Fortunately, we'd bought an automatic gdrive which backed up automatically without any input needed from a digitally challenged operator. We asked the Time Machine to restore the operating system to that which preceded Mavericks. After a half an hour of whirring and exchanging, it accomplished that which we hoped it might. The previous OS was reinstalled, the computer recognized the printer once again, email programs came to life, and life returned to normal. I had wondered at the time why Apple was making those who wanted Mavericks to engage in a lengthy (10 hours for us) download instead of selling an installation CD with the Mavericks OS on it for 50 to 100 bucks. Now I understand why it stuck with the download; Apple would have been deluged with demands for refunds; with this, no money exchanged hands and no demands were made on Apple. It is, however, an upgrade not yet ready for prime time unless you like aggravation and heartburn. That Mavericks will provide in that spades, for those who are swayed by the well produced come-ons distributed by Apple on its websites. But if you want a nice little quiet upgrade in your OS to improve your computer and increase your productivity, Mavericks is not the upgrade for you.

In short, I resent being made a free guinea pig for Apple, a tester without portfolio or pay, recruited by my own hand to test their Operating System, and discover what they need to do to improve it. When a car won't run, or when it does it is erratic and controls it not, it is time to move it on to another.

Pros

integration with iCloud

Cons

After booting up and the Finder comes up, there is a big lag trying to launch an application, lots of bounces on the dock. Got couple of applications running, more lag when trying to switch to another application and doing something. Better with Mac OS 10.8.

Pros

Better battery life on my MacBook Pro.

Cons

None that I can see

Summary

Not sure what "mac-heath" is ranting about. I haven't had any of the problems that he reports. None. Maybe he is just selling his blog.

This is still in Beta at the time of my review. Beta is not General Release. One could expect bugs in Beta, but again, I haven't had any trouble with it.

Pros

None found after three weeks.

Cons

It's not ready for release and the redesign is ill considered. Too many probelms to list here: crashes, network drops, bugs, no more native sync, chaotic redesign that disrupts work flow. See my description here: http://mavericksos.blogspot.com

Summary

I have written up and posted most of the major problems on the following blog:


Chief among the defects are frequent slow downs and crashes involving apps that deny access to the processor to keep the processor cool. The apps are called kernel_task and SystemUIServer. The crashes happen running native apps email and safari and skype and ms word 2008, no heavy use, no music or video, just work-a-day apps.

Lots of little things to upset your workflow. Going from recognizable three-dimensional icons and over all appearance to washed-out, over bright two dimensional "cleaned up" or "uncluttered" appearance that makes everything harder to use.

Bought a high end mac book retina with this OS on it, an expensive mistake.

This is Apple's "Vista" only maybe worse because it cannot be uninstalled.

Pros

It's better than windows and Mountain Lion OSX.

Cons

It's worse than snow leopard.

Glitches with Java

Hid "Quick look" feature inside a menu, and is no longer available quickly as it is meant to me.

Folder tags are now little dots instead of bold colors. The point of a tag is to clearly see what I marked, unfortunately, the change to the dot makes me look for the dot now so I can find the folder i'm looking for... hmmm... how about a tag for a tag Apple?

Summary

It seems the developers are not getting much sleep, or are just the good ones are leaving apple... hope one of the good ones starts a new OSX that is superb!
