Enterprise Wi-Fi Issues with Yosemite

MacBook Pro (Retina, 15-inch, Mid 2014) - But also tested on other older models running Yosemite.
Yosemite version 10.10.2 (This has been an issue with all versions of Yosemite)
The company that I work for has a wireless profile that was built that will authenticate (on login) with our AD login credentials. It works great upon login. But with any device that has been updated to Yosemite, if the device is put to sleep or if you leave the wifi connection for one reason or another, it will not allow us to reconnect. Even if we enter our AD credentials when prompted. It simply will not reconnect to the Enterprise Wi-Fi. The "quick" solution is to log out of the OS and log back in.
Is this a common issue?

Dear Strottier

Issues with Yosemite, can I downgrade to Mavericks or Mountain Lion and downgrade Apple Apps to work with older OS X

Hi
I am having several issues with Yosemite, mainly disappearing folders (title / name) but no folder or more importantly no previews of .mov or other video files nor unable to open them. I have years of these files that I want to edit in FCP X.
I have upgraded all my Apple apps so they now work in 10.10.2, but I want to revert back to Mavericks as a second partition for video work.
Is there any way I can reinstalled an older OS and downgrade my Apple apps like FCP X and Aperture so I can open, edit and produce dvd / bluray of these files.
Thanks in advance
Matt

Thanks perermac87. I'm can make a second partition on ssd for mavericks as plenty of space, but final cut x 10.1.4 I have now needs Yosemite to open. So how can I also download older versions of my apps from the App Store?

I have a 2012 Macbook Pro and the GPU is causing issues with Yosemite. How can I resolve this issue?

I have a 2012 Macbook Pro and the GPU is causing issues with Yosemite. There are a number of issues I have run across:
If I have four tabs open on Safari then I start to get a flickering on the screen from the GPU refreshing
When I leave the computer alone for more than 20 mins the screen saver should start -- what happens is that the screen goes to black. When I move the cursor I do not get the login screen. I have to reboot
FireFox Web browser will not run
I get issues with the computer running very slowly
I have already turned off the transparency option in settings. Any ideas??
Cheers

MacBook Pro, OS X Yosemite (10.10), GPU / Video Card with Yosemite

Do you have more than one OS on the Mac?
You may want to look at something like http://bjango.com/mac/istatmenus/. This has a Free Trial window, but it is a commercial application. If there are any heat/sensor issues, this may help.
A SMC Reset or PRAM/NVRAM reset may also help.

Issues with Yosemite and Safari on extended monitors

I have Yosemite installed on a Mac Pro with 3 monitors attached to it. As soon as I installed Yosemite, I noticed that whenever I tried to fill in text input fields on a web page, the things I typed in would start blinking. And when trying to backspace to correct any typing errors, the field would remain the same and continue blinking. It was very annoying because it was very difficult to enter anything into text input fields.
My brother and an officemate who also had Yosemite installed on their computers were not experiencing this issue so I tried to isolate the problem on my system. What I discovered is that Safari behaves as it should when it is displayed on my main monitor. But whenever I move the Safari window over to one of the other monitors, any text input field on a web page would be next to impossible to type text into. Other input fields, such as dropdown list boxes, act weird also.
I should add that this only happens with Safari. Firefox and Chrome do not behave this way on any of the monitors. Other apps also run fine on the extended monitors. It's just Safari that misbehaves.
Has anybody else experienced this problem. Is this a known bug? I tried doing a search here in this community and on the internet itself but have not found anybody else complain about this issue.
Thanks.

Hi all, I too am expieriencing similar issues.
I am running a 2012 6core 3.33 Mac Pro with two ATI Radeon cards driving 3 27" LCD Cinema Displays. One of the Radeo cards (1) drives the outer 2 screens and the other card (2) drives the centre screen alone.
I upgraded from Mavericks to Yosemite 10.10.01 after being very pleased with it running on my Macbook Pro for a few weeks.
My center screen had issues immediately rendering certain pages in Safari, the App Store and Mail. In particular the google page when it has live search results showing, the App Store updates page also renders badly, and some emails in Mail that are html also don't load as the should. Generally its the top of the page flashing, or the text input box on a page like this thats effected.
I did a fresh install of Yosemite and it didn't fix the problem.
I notice when I drag my safari window from the outer screen to either of the side screens, the problem goes away and returns when it comes back to the centre screen. I swapped over the mini display ports so that graphics card 1 drives the middle screen and graphics card 2 drives the outer screens and the problem moved to the outer screens.
I am still on Applecare so I called Apple and a senior tech took a look at the issue on my screen remotely. He decided on replacing the graphics card. This is being sent now so I report back once its installed to let you know if it made a difference.
I am also going to try swapping out one of my cards with another colleagues card to see if I can establish if its a bug in Yosemite or an issue with a specific ATI card, or indeed just a problem when you run two cards.
In the mean time I would be interested to hear if any of you guys found a workaround.

Mac Book Pro 13 inch Graphics Issue with Yosemite

I have a major graphics issue with my Mac Book Pro mid 2010 after upgrading to Yosemite. I have a 2.66ghz with 8gb memory and 320M 256 MB NVIDIA graphics card. Since upgrading to Yosemite (after a clean install) I have had the following issue that are driving me crazy;
When I use more than one program my screen displays large blocks of unrecognisable fuzziness. I have two screen working off my Mac Book Pro, one is the Apple 27 inch theatre screen.
My system works slow despite have ample free memory available on my disk (over 150gb)
It is becoming an increasing concern as this issue builds up over the day to the point where I need to reboot to fix, however as soon as I use Photoshop the system almost grinds to a halt. Other issues that are bearable but ned addressing include;
Keyboard often does not work on startup and requires you to pull out the keyboard and reconnect (intermittent).
Lost email when sent (intermittent). I had hoped that this would be fixed in this updated release.
Laggy behaviour in general.
I am hoping someone has an idea to fix these issues or are also sharing my frustration. Can someone suggest fix as this is not a workable situation for Mac book Pro users and 2010 is not that of an old computer. Apple???

So you erased your drive and installed 10.10 and then 10.10.1 and everything else was t hrough Setup Assistant, through reinstalls, or through TimeMachine restore?
A four-year old laptop may be at the point where that small older gpu and processors have more trouble.
you might want to hold off and go back to Mavericks or whatever you had - hopefully you cloned that system before doing clean install, upgrade to 16GB, maybe throw in an SSD... or save and get the next MacBook Pro to come out.
And you checked your apps at http://www.roaringapps.com for compatibility.
Might help just to see what if anything shows up in output from Etrecheck.
Probably thought this was laptop MacBook Pro, it is not, probably best moved to Yosemite forum.

Ram Preview Issue with Yosemite

Hi, I have updated to OS X Yosemite, I am using AE 13.1.1.3, and now I am having an issue with RAM-Preview that makes working with AE problematic: When I start the Preview by hitting "0" on the Numpad the Ram Preview starts, but I am not able to stop it anymore until it has rendered to the end of the work area.
It is also strange that I am able to move keyframes while it renders.
The Shift-Ram Preview is also affected by this bug.

There is a known bug with Yosemite and the RAM preview, but your issue sounds different. Anyway, see the known issues here: After Effects good to go with Mac OSX v10.10 (Yosemite)

Fontographer PS fonts issue with Yosemite

I have created a number of PS fonts (.otf) with Fontagrapher 5. They have been working flawlessly ever since on my MacBook Air (mid 2012) 8GB RAM and 512GB SSD.
Since moving yesterday from Mavericks to Mac OS X Yosemite, things are terrible. All fonts created with Fontographer are not displaying and printing correctly …. my 6 indian music books and numerous documents in hindi/english diacritical are thus unusable. I tried with Nisus Writer Pro, Text Edit and Mellel to no avail.
Checking with the Apple software FontBook, it says all my Fontographer Fonts are « usable » (green ok check) and that there is no conflict/problem. To be sure, I removed all factory fonts which could potentially make problems (orange warning), rebooted the Mac but, despite that, nothing works properly. Fonts are incredibly SCRETCHED on display (space between characters is huge) and some of them don't print as they are displayed. I also naturally updated the printer (Xerox Work Center 6605 DN) driver to the latest Yosemite compatible version (oct.16, 2014) but that doesn't change anything. I also tried different ways of making pdf from the different word processors but the same thing occured on pdf.
Please, kindly check and inquire about this important issue with Apple fonts experts. Number of us, using Fontographer Fonts, must be facing the same incompatibility with Yosemite.
Please do let me know what I can do to solve the problem. I don't even know how I can downgrade to Maverick yet.
Thanking you in advance for a quick reply
Patrick MOUTAL

Well, Kurt Lang did solve my problem and I won't ever be enough thankful to him. He tried one of my font and took the time to examine it with FontLab Studio. In case other persons experiment the same type of troubles, I am pasting the mail I got (along with the corrected font) for info :
Hi Patrick,
I did find one issue in particular. OpenType fonts should have a UTM setting of 1000. These were at 2048. So I changed those and had FontLab Studio rebuild the names (I just let it do its thing).
The originals you had sent wouldn’t even appear in Office 2011. The rebuilt ones do, though for whatever reason, bold italic won’t show. However, you can click the italic and bold buttons and the correct font is used. Otherwise, the new fonts all work as expected in Photoshop, Illustrator, InDesign, TextEdit and others. I tested them in both Mavericks and Yosemite.
Can’t guarantee success, but give these a shot.
Kurt
That guy is an angel. He spent a tremendous amount of time examining, testing on Mavericks and Yosemite and on several apps until resolving the problem. Too helpful, too nice and too competent. That's a treat.

Lightroom & Photoshop Issues with Yosemite

Hi. I am new to this so please forgive and errors or omissions in the information I am about to give below:
Since upgrading to Yosemite 10.101, I have had issues with Photoshop not working properly. I am using the Creative Cloud versions of photoshop and they are up-to-date. The photoshop issue is that after an image is opened, the screen within the application turns completely black. You can't see the image although photoshop doesn't crash. I believe Adobe are looking into this issue.
I have installed the new Safari update tonight and now all of my images in Lightroom are pixelated. It was fine 10 minutes before the update which is when I was using it last.
I have a 2013 imac 2.9ghz intel core i5 with 1TB storage of which half is free
8gb 1600 Mhz DDR3 Ram
NVIDIA GeForce GTX 660M 512 MB
I am trying to understand:
- Is my iMac still powerful enough to run these programmes following the upgrades to the IOS and other apps (I would hope so because it isn't that old and cost a fortune! )
- Should I be raising the issue with Apple or Adobe in terms of not being able to use the Creative Cloud Photoshop and Lightroom? I am paying a monthly subscription for the packages but now can't use either of them due to the upgrades.
If anyone has any ideas/suggestions, I would be really appreciative. If I haven't explained the issue clearly enough, please let me know and I can try to elaborate!
Thanks.
Kieran

[discussion moved to Downloading, Installing, Setting Up forum.]

Are there any known issues with Yosemite (iMac/Intel)?

I have seen reported issues with Wi-Fi, Interrnet connection, and ethernet. Are these still valid concerns at this point - or has the OS been updated?

Those never were valid concerns. A very small percentage of users had issues but by and large most of us have had no problems whatsoever. However before upgrading you should always make a backup of your entire system in the event that you want to downgrade to your previous state. Make sure that you have at LEAST 4gb of ram and more is better. Also check to be sure that applications you depend on are compatible or upgradable for Yosemite.

Compatibility Issues with Yosemite?

I have an older version of CS (Illustrator, Photoshop, and InDesign—5.1-5) Would upgrading to Yosemite be ill-advised?
Anyone? Anyone? Buehler?

See this earlier thread: Does InDesign CS5.5 work with Yosemite?

Problem with connecting to a website. Just purchased a new iMac with Version 10.10.2 Yosemite. Once in a while I have trouble connecting to a site. It takes forever. Is this an issue with Yosemite or my internet service?

I purchased this iMac in Feb. 2015. When I try to connect to a web site using Safari or Google Chrome I usually have no problems getting connected to the site. But maybe once a day I will try to connect and I will see the blue progress bar at the top of the screen showing it is trying to connect and then it just stops. It may take a couple of minutes before it connects to the site.
Would this be a problem with OS X Yosemite Version 10.10.2 ? Or would this be a problem with my internet company?
Thank you,
Laurie

Hi lauriefrommi,
Welcome to the Apple Support Communities!
i understand that you have some intermittent webpage loading issues while using Safari on your Mac. In this situation, to ensure that Safari is working as it should, I would suggest reading over the attached article and using the information to make sure Safari has no unsupported third-party add-ons.
Unsupported third-party add-ons may cause Safari to unexpectedly quit or have performance issues - Apple Support

Macbook Pro Mid 2012: Issues with Yosemite update, graphics, and hard drive.

MacBook Pro (15-inch, Mid 2012)
Processor: 2.3 GHz Intel Core i7
Memory: 4 GB 1600 MHz DDR3
Graphics: Intel HD Graphics 4000 1024 MB
I've used 192.8 GB
Operating System: 10.10.1 (14B25) YOSEMITE UPDATE
I've been experiencing problems with my Macbook Pro shortly after the two year mark of when I've purchased it. There are a few things that are going on. I recently verified my Macintosh HD disk through disk utility and it stated in red that there was an incorrect number of file hard links & then error: This disk needs to be repaired and to restart and then press "R". However, everything before that seemed to have passed. I have everything backed up on an external hard drive and use the time machine frequently. Another thing that has been happening, usually when I'm opening one my adobe programs, is that my screen will go white for a minute along with unidentifiable pink glitchy shapes that don't move. My computer has not been running like it used to and is running slow, freezing, and periodically going white --- as I just mentioned before. I just know that something isn't it right. I've been having to restart my computer by manually pressing the power button more than I've ever had over the past two years. I always work on my computer on a hard surface in a cool area & my fans seem to behaving okay. I also recently installed the Yosemite update for the mac sometime during this past November too and noticed slower running speed, more freezing, and longer times to boot up afterwards. Please speak up if you're experiencing problems with your 2012 Macbook pro too and especially after downloading the Yosemite upgrade. I don't see how it's in any way acceptable that I should have to deal with issues pertaining to my graphics card. Sorry for this post being a little all over the place.

Hello brousch,
Thanks for using Apple Support Communities.
From your post I see that your Mac is spontaneously restarting whenever you see a certain animation on your screen. This indicates your Mac is getting a kernel panic caused by that animation. If you'd like to learn more about kernel panics, including how to troublshoot them, please take a look at the information in the link below.

HDCP display issue with Yosemite and Macbook air

Hi - Sorry if the question has been asked before and answered.
I have an issue where since I have upgraded to Yosemite, I cannot play any of the movies I bought prior to upgrading and I can even play trailer from the iTunes store...
Any ideas?
Thanks

Too bad this didn't help.
HDCP errors can also occur when your display settings are incorrect and when you have non-original / non-Apple display software installed. Think a special driver to support a specific type of external display, or a remote viewer application like TeamViewer or AirParrot.
If you're having the HDCP error with an external display, disconnect it and test with the MacBook Air's own display.
If the issue persists on the MacBook Air's own display:
To restore your display settings to factory default: do a PRAM reset:
http://support.apple.com/kb/PH14222?viewlocale=en_US
Shut down your Mac.
Locate the following keys on the keyboard: Option, Command (⌘), P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on your Mac.
Immediately press and hold the Option-Command-P-R keys. You must press this key combination before the gray screen appears.
Continue holding the keys down until your Mac restarts, and you hear the startup sound for the second time.
Release the keys.
If you have special software installed, it would be best to try to boot the computer to safe mode:
http://support.apple.com/kb/PH18760
Choose Apple menu > Shut Down.
After your Mac shuts down, wait 10 seconds, then press the power button.
Immediately after you hear the startup tone, hold down the Shift key.
You should press the Shift key as soon as possible after you hear the startup tone, but not before.
Release the Shift key when you see the gray Apple logo and progress indicator.
If that doesn't solve it, peruse your Applications folder in the Finder and see if you can delete unwanted video / viewing-related applications.

Exchange sync issues with yosemite

I am having problems with my Exchange Server since upgrading to Yosemite.
I have my Mac Mail / Calendar / Contacts apps set up with my Exchange server, and am also running an iPhone 5 and iPad 4.
I have Outlook 2011 for Mac also installed on my Mac Book Air.
The issues I have are as follows:
My iPad and iPhone work fine. New contacts can be added / existing contacts changed as can appointments. These all sync fine with my exchange server, and update on all my clients & devices.
I can add new appointments via my Outlook 2011 for Mac client, but cannot change existing ones. I can neither add new, nor change existing, contacts through Outlook.
My Mac Mail app will add new appointments and sync to Exchange fine, but will not allow me to change existing calendar entries.
My Mac Contacts app will not allow me to add new, nor change existing, contacts.
I have progressed this as far as I can with Fasthosts (my domain registrars and email hosting company) and they can find no issues their end.
It's very frustrating - anyone else out there have the same issue or is it just me!?

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

User issues with Yosemite

I am desperately hoping someone can help answer this.
Since converting over to Yosemite I have had a lot of problems with my iMac. Mail crashes with Exchange, internet connection either via hard cable or wifi goes on and off, different programs closing and reporting errors.
So after doing the usual disk repair etc and various looking around I decided to create a brand new user with admin rights.
The only thing I have done was to add my exchange email account and keep it running. So far so good and no problems. Also Safari runs and connects no problem.
So now I am thinking my old user account is the problem. Everything seems quick and easy as it should be, so something is causing my old user account to be the issue, finding that issue could be like looking for that needle!!!
So....
1) can the existing user account/library be fixed?
2) am I better to migrate everything over to the new user and how would I do this?
3) time machine doesn't work with new user, how do I change this and be able to access it from new user?
4) dropbox, I take it I just download and let it download all the files again?
Many thanks in advance
Dan
