Dvd problem after yosemite

2010 MBP - played a commercial DVD before update to yosemite - now it refuses to play. Some other DVD's play fine. Disk is pristine - not dirt or scratches. It looks like a stamped DVD. Were there some new restrictions added to the drives in Yosemite?

Ok, this is weird. I went to my MacPro running maverics - DVD played fine. I make a direct copy to DVD-r. It played fine too. Took both disks to my iMac running maverics - both played there. Went back to MBP, neither would play. I opened system prefs, went to language and region - all looked fine. Closed it, tried original disk - AND IT PLAYED FINE! I tried the DVD-R - and it refused to play. Tried the original and it played fine........
So either this is all and odd coincidence or there is some issue still with some disks in Yosemite. I want to upgrade all my machines to Yosemite but not if I'm going to end up loosing access to some of my content of DVDs.

PS CS6 having printer problems after Yosemite upgrade.

I've seen a lot of people having problems with this, and zero answers from Adobe. I'm running Photoshop on a 2012 iMac. I don't know what exactly triggers the problem, but it occurs when I'm changing the print settings for a document. All of a sudden I get this message:
There was an error opening your printer. Printing functions will not be available until you have selected a printer and reopened any documents.
And nothing, nothing will enable me to print from Photoshop ever again, except re-installing the whole program. This is a pain, of course, and I lose all my settings.
There seems to be an incompatibility between PS and older macs running Yosemite. I have not had the problem with my 2014 MacBook Pro--it prints fine from PS with the same printer. (A CanonMG5320, FWIW, but it seems to be happening to people across a range of printers.) I spent a lot of time in a fruitless text chat with someone at Adobe who disappeared after a bit and left me hanging.
Whose responsibility is this? Adobe's or Apple's?
I just wish someone would fix it.

Probably either Apple's or Canon's. There have been a lot of issues with he new Yosemite. First off, are you running the latest version of Yosemite (10.10.3)? Have you tried Re-installing the printer's drivers?

Secure Connection Problems after Yosemite update

Hi all
I'm using a MacBook Air 2012 and since upgrading to Yosemite, I have had a lot of issues using an Ethernet connection. I was using the same Ethernet connection for Mavericks and there were no problems whatsoever.
None of my apps which use the internet can connect. Examples include Skype not signing in, my Mail app not connecting and being unable to connect to the App Store.
When using Safari and Google Chrome I cannot access secure websites (https), however on Firefox I can access the majority of secure websites. Non-secure websites (http) are not a problem on any browser. Error messages on Safari say "Safari can't open the page (web address) because Safari can't establish a secure connection to the server." On Google Chrome the error message reads, "The connection to (web address) was interrupted."
I have tried and failed with numerous different suggestions including:
Ensuring correct time and date
DNS Flush
Changing Network Location in Preferences
Setting Network Location to Automatic in Preferences
Turning Firewalls/Anti-Virus Software off
Typing the following commands into the terminal:
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist
sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist
Any help would be greatly appreciated!

Start up in Recovery mode. In the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. While in Recovery, you'll have no access to your saved bookmarks or passwords, so make a note of those before you begin, if they're needed for the test.
Test. After testing, restart as usual and post the results.

Ricoh printer problems after Yosemite upgrade

My Mac is on a small business server that also included a Ricoh MP C5501 printer. It worked fine before the Yosemite upgrade but after that upgrade plus use of the Ricoh Yosemite driver I can't get anything to print. Someone says that it is a Postscript problem but I don't know to fix that. Is there a proven process to address this issue?

Hi there DirectorCHA,
I would recommend taking a look at the troubleshooting steps for printer issues found in the article below.

may help, but Kodak needs to update their drivers.

FCP X problems after Yosemite 10.10.2/iTunes 12.1 update

FCPX 10.1.4 on Yosemite 10.10.2 w/ iTunes 12.1 installed on MacBook Pro (Retina, 15-inch, Mid 2014), 2.5 GHz Intel Core i7, 16 GB 1600 MHz DDR3
After installing the Yosemite 10.10.2 update and the iTunes 12.1 update, FCP has been brought to a halt on new projects. When importing a ProRes 422 clip (NTSC SD, 29.97, ) into a clean/empty library results in what appears to be a hang while generating audio waveforms for the clip. I am not able to skim the clip in the viewer. If I create an empty project, and then write the clip to the empty timeline, FCP also appears to hang on audio waveform generation (although Activity Monitor does NOT reflect an unresponsive app, and there is not spinning beach ball, etc.).
I can open an existing library, where waveforms and thumbs have already been generated, and successfully skim/scrub clips and project timelines.
Screenshot of the background process window:

Hi Luis,
ok i have just completely wiped it off my system with all traces trashed..
i will go ahead now and install FCPX version 10.1.4 as i see it on the app store and shall report back once re-installed with results..
thank you for your suggestions..
btw attached is a screen shot of some info incase..

3g modem connection problems after Yosemite upgrade

Typing problems after Yosemite

This is my first time here, so I'm going through a learning process (and I suspect I may be on the wrong page so apologies in advance). Since upgrading to Yosemite on my one year old Mac mini, typing with either a wireless or a USB keyboard has become a major frustration. An apostrophe inserted in a word causes the remaining letters to behave erratically and the "e" as in "I've" ends up at the end of the sentence. Has anyone else experienced this? Any solutions?

Does it happen in Safe mode?

My MacBook Pro's internal SuperDrive has stopped recognizing CDs/DVDs after Yosemite install

After upgrading to Yosemite, my MacBook Pro's (early 2011) internal SuperDrive has stopped recognizing CDs/DVDs after Yosemite install. It takes them in and will eject them with the keyboard button, but they will not mount. Disk Utility shows the SuperDrive and shows the inserted media, but will not mount the disk. That button is grayed out. Please help! I still have training libraries and music I access on such media. Thx!

UPDATE: I discovered some forum posts about a similar issue with Mavericks that recommended re-installing the system to fix the problem. I realized that I rarely restart my computer unless there's an update that requires it, and decided before undertaking a full re-install of Yosemite to simply restart my computer again. THIS WORKED! The SuperDrive is now mounting CDs and DVDs. Not sure what the issue was, but if anyone else has this issue I hope this will save you hours of frustration.

Wifi problems on Macbook after Yosemite upgrade

I am having very serious problems with wifi connectivity of my Macbook Pro Retina after upgrading for OS X 10.10 by the end of October .
Of course this has a great impact on system usability since almost exclusively use wifi to connect to the network.
I must say I never expected that in Apple world a problem of this magnitude take so long to solve!
After trying various proposed solutions without result, two weeks ago in a user forum I found a simple turn around that effectively minimizes the problem on my Macbook.
Deactivating Bluetooth Wifi connectivity becomes less unstable and can work continuously with the networked PC. There continues to be an abnormally high rate of errors affecting eg Time Machine but the wifi connection does not drop.
It's a little ridiculous I can not use my Magic Mouse but it is less problematic that not to have Network!
But someone can direct me to a date that provides for the effective resolution of this problem by Apple? Or at least that the problem has been recognized and is being done something to fix it?
My system is yet under warrant. Should I activate the warranty and ask for the replacement of the Macbook? From what I've read not all users have this problem with Yosemite.
Can someone please explain to me the reasons why I have the problem and others with theoretically equal machines do not have it (it that is the case)?
Thanks in advance,
Fernando Ribeiro

I installed last OS X update, 10.10.3, and the problem is completely solved.
The problem, Wifi+Bluetooth, is clearly addressed on the update notes.
Now I am working with Magic Mouse, Bluetooth, while navigating on the Internet via Wifi.
Thanks

Encountering problems after updating to Yosemite

Hi! I updated my iMac (Refurb 2011 27" iMac, i5, 2TB HD, 8GB RAM, 1GB VRAM), Yosemite from Mountain Lion, after getting a new iPhone 5s last week. I had to update iTunes, and to update iTunes, I had to update my OS.
Problems after downloading:
- USB ports are intermittently working.
- Illustrator CC will freeze my entire computer (rainbow beachball not even rotating). Happened twice already. Have never experienced a complete freeze before.
- iMac turned itself off from sleep mode. After arriving home from work, the computer would not turn on. I thought perhaps I was having a power button issue (I've already had the shell replaced once), but after unplugging, waiting 15s, and replugging in, it turned on. I guess it's possible the power went out, but I doubt it.
- Last night, it restarted from sleep mode after 5-10 minutes (freaked me out since I had gone to bed). I have read this is a common problem; surprised it hasn't been patched yet. I just turn it off now.
- Every time something happens and I have to restart, my background is back to default. (minor gripe)
I have done PRAM and SMC resets.
Is it worth going back to Mavericks, or are these addressable problems? I thought since I had waited some time since release, the kinks would have been worked out by now (it's been 6 months, right?). If I was just using this computer for fun I wouldn't mind as much, but it's really messing with my freelancing work flow.
Thanks for any help!

great Problemes after installing Yosemite (10.10.2 ) with Photoshop CS6....The program crashes --last time 10 times during my work session..wacomtable doesnt work..it is slow...and get error messages about the graphic card....It s a Terror to work with my beloved Photoshop!

The Yosemite upgrade very often damages existing Photoshop installations. Thank Apple for that.
You need to uninstall and re-install Photoshop, then apply all the Photoshop upgrades from scratch.
But first, give us details about your setup:
BOILERPLATE TEXT:
Note that this is boilerplate text.
If you give complete and detailed information about your setup and the issue at hand,
such as your platform (Mac or Win),
exact versions of your OS, of Photoshop (not just "CS6", but something like CS6v.13.0.6) and of Bridge,
your settings in Photoshop > Preference > Performance
the type of file you were working on,
machine specs, such as total installed RAM, scratch file HDs, total available HD space, video card specs, including total VRAM installed,
what troubleshooting steps you have taken so far,
what error message(s) you receive,
if having issues opening raw files also the exact camera make and model that generated them,
if you're having printing issues, indicate the exact make and model of your printer, paper size, image dimensions in pixels (so many pixels wide by so many pixels high). if going through a RIP, specify that too.
A screen shot of your settings or of the image could be very helpful too,
etc.,
someone may be able to help you (not necessarily this poster, who is not a Windows user).
