Since Yosemite my Macbook 11inch mid 2011 (supports Thunderbolt) does not see the second thunderbolt display anymore.
My MacBookPro 13inch Early 2013 works fine, but it swaps the screens after an (re)boot.
Does anyone else experience these problems and/or have solutions

Hello ROBLAHAY,
I'm sorry to hear you are having this issue with your MacBook Air. I also apologize, I'm a bit unclear on the exact configuration you are describing. If you are talking about using two external Thunderbolt displays (in addition to the internal display) with your Mid 2011 MacBook Air 11-inch, you may want to be aware that only a single external Thunderbolt display is supported on that model, as noted in the following article:
3. How many Apple Thunderbolt Displays can I use with my Mac in OS X?
The table below indicates how many Thunderbolt displays can be connected to Thunderbolt-capable Mac computers in OS X.
Computer
Maximum connected displays
Thunderbolt-capable Macs with Intel HD Graphics 3000 integrated graphics can support one connected Apple Thunderbolt Display (27-inch).
MacBook Air (Mid 2011)
MacBook Pro (13-inch, Early 2011) and (13-inch, Late 2011)1
Mac mini (Mid 2011), 2.3 GHz
Mac mini with Lion Server (Mid 2011)
One Thunderbolt display

After upgrading to yosemite my macbook pro late 2011 does a random sound from time to time.

After upgrading to yosemite my macbook pro late 2011 does a random sound from time to time. Its completely random and i already checked all apps in use and its not from them.

Sounds like Notifications app.
Maybe some other app. In SystemPreferences->Users&Groups->LoginItems tab: remove all entries with the minus sign underneath. This will not uninstall anything, you have to start those apps by hand now. Restart.
Still there?
Yes: Restart again while holding the shift key, this will start the mac in SafeMode: only the necessary items are loaded to run.
Still there?
Yes: Make an etrecheck list and post it here.
No: Restart, put the items in the LoginItems back, one by one, restart after each entry, and you will find the "culprit"
Please report accordingly. I will be back in 24 hours.

I just installed ios7 on my iPhone 4s. It seems to be working fine but all of the apps I had previously installed are gone. They show up in my app store as purchased, but the shortcuts are gone. Does anyone know how to get the shortcuts back? Thanks!

I updated via my iPhone 4s. The apps were on my iPhone 4s. That's all the information that I have. The update to ios7 seems to have gone smoothly - everything else is working, phone texting, email, internet, etc. But all of the apps I had installed over the past year are no longer showing up as shortcuts. No facebook, no twitter, no espn, etc. They are all still listed in my app store as purchased, but the shortcuts and my folders are gone. Thanks.

- Charge the iPod for half an hour. Then reset the iPod:
Reset iPod touch: Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
- if still not working, connect to your computer. If iTunes sees the iPod, restore the iPod.
- If still problem, place the iPod in recovery mode and then try to restore the iPod. For recovery mod see:
iPhone and iPod touch: Unable to update or restore

MBA mid-2012 does not see external display on wakeup

My mid-2012 MBA does not see external displays on wakeup. VERY annoying
I have a BenQ 24" HD display connected by HDMI and it is not seen by the Air on wakeup. I have to open the laptop, pull the mini-DV plug out 3 or 4 times before the display is recognised - some of the time. Most of the time requires a reboot with multiple cable/plug inserts.
What an absolute POS this mid-2012 MBA is! Apple finally fixed the garbage colours on external displays in 10.8.4 but the issue of recognisisng external displays remains. Its a crock. Totally regret buyiing this POS.
Have reset PRAM, SMS, cleared prefs etc etc ad nauseum. No solution with any of them. After almost a year of this garbage, the laptop is close to being thrown out as e-waste.

I have a I phone 4. I recently changed carriers to straight talk it was working fine but I deleted the vpn file on accident. Now I can't get cellular data. Does anyone know how I can reinstall that file or download it somewhere?

I own a I phone 4. I recently changed my service from AT&T to Straight Talk. It was working fine but then I deleted the vpn file on accident. Now when I try to get on line I get a message that I am not signed up with a cellular data network. Does anyone know how I can retrieve or download the vpn file?

I have taken it back to the Apple store genius bar, but they say they don't see anything wrong. Well unless you use it all day and experience the problems when they happen, you wont see anything wrong. But there are lots wrong with it. But this would be the same store as I purchased the phone. And they backed up my old Iphone 4, but were not able to get anything to load back onto my new phone. So, I lost pretty much everything. But over time, some of my contacts have started showing up, although i am still missing over 800 of them.

After sleep, retina MacBook Pro (Mid 2014) does not recognize usb connected mouse movement

After sleep, retina MacBook Pro (Mid 2014, on 10.9.4) does not recognize usb connected mouse movement. I have tried a generic usb mouse and my Razer Deathadder usb mouse. Both mice work before sleep; but after sleep, the computer no longer recognizes mouse movement while still recognizing the mouse buttons when pressed. Any idea why this is occurring?

My iMac (mid-2011) does not start and AHT is OK

I had a similar issue last June and after I carried my iMac to Genius bar, they decided to replace the HDD on warranty. It solved partially the issue but after uninstalling flah player, everything was fine. So, 3 days ago, when this problem occured again, I uninstalled and reinstalled flash player.
But this time, it solved the problem only for one day (it should mean that is is not related to 'Flash"), and I have not been able to start it ever since.
I tried all kinds of resets and ran a bunch of tests with no result.
When I do the AHT (Apple Hardware Test) from disc2 , result is perfect and AHT does not find any hardware problem.
I tried to boot from disc1 (installation disc) but no way to boot. It could be that I have updated OSX 10.6 to Lion 10.7 and disc is 10.6???
It seems I am stucked. Any idea will be welcome

Have you tried a safe boot, by holding the shift key down as you boot? That will take longer than a regular boot, as it's doing some disk maintenance. If that works, try a normal boot.

Deleted files now Macbook pro 13 2011 does not boot up

Tried following some instructions to delete search.genieo an safari and deleted some files. Now my Macbook pro 13 does not boot up at all. All I see is the screen with small apple and the running circle below indicating it is thinking. any clues anyone. Thxs

Just for the record, in case someone with the same problem stumbles across this topic later, I'll repeat the advice I gave you on another topic:
You did not follow the instructions precisely, and now you have suffered the fate that the giant red text on that page warned you about.
At this point, you will need to try the recovery instructions posted at the end of that page.

Trackpad of MacBook Pro mid 2009 does not respond to the first click/tap

Have the following problem and wasn't able to find any sollution here somewhere
if I click on a link or choose a checkbox or do anything by clicking it does not work with the first click/tap and I have all settings right.
a PRAM reset had no effect on that problem.
so I still have to click/tap several times to access a menu, a safari-tab, or anything else…

thank you.
still I am not sure if it really solved my problem, but it looks very good.
was a bit irritated in the beginning, because I got no feadback if I had done the SMC reset right.
If the problem will be back too soon, I will continue this discussion.

IMovie for iPad 3 does not see my camera roll anymore

In iMovie when I tap the photo or video icons it does see my camera roll anymore.

Go to Settings - Privacy - Photos. My guess is that you do not have iMovie switched "On"

IMac (Mid 2011) Does not wake up after long sleep

Hi People,
Having issues with my Mid2011 iMac (21,5", 2.7GHz). Just upgraded to 12GB RAM (2x2GB original + 2x4GB). System runs fine, no issues.
But when system goes to sleep for a longer period (a few hours) it will not wake up again. Neither by Keyboard/Mouse interaction (Bluetooth as well as USB) nor by pushing the powerbutton. I also performed the PRAM and SMC reset as described in the apple support resources.
Feeling a bit lost. Any Ideas?
Thanks in advance for any help!

Addition:
Performed a test of the RAM with memtest. No erros found. Also forget to mention that the Mac has also Software updates and firmware updates installed.

Yosemite bug? Itunes Home sharing does not see library on additional drive

I have a 2011 iMac 27" with two internal drives, an 256GB SSD main drive and a 3TB hard drive (/Volumes/Media). My iTunes library is held on the 3TB drive for space reasons, and the correct path to the library is in Preferences > Advanced. I have enabled Home Sharing, and have made sure that the sharing tab is correctly set to allow all content to be visible.
On my 2010 Macbook Pro, I can connect to the iMac iTunes through Home Sharing (there is an entry in the drop down list at top left), but I can see no content at all.
If I change the path to back to the default library in Preferences on the SSD drive (i.e. /Users/david/Music/iTunes/iTunes Media) rather than the real library (/Volumes/Media/Itunes/Itunes Media) and import a song, then that song immediately becomes visible on the Macbook Pro.
Therefore, the actual mechanism for streaming the content seems to be working, but it only seems to work if the library is on the default disk.
Is this

Solaris does not see second cpu

I have put together the following system:
Asus A7M266-D mobo
2 - Athlon MP 1.6+ cpus
2 - 512 MB DDR PC2100
Maxtor 60 gb hd
Matrox G450 agp video
mpstat shows only cpu 0. Any thoughts on how to get both cpus running?
Allen

Allen,
What does the following command indicate:
psrinfo -v.
Do a man page on mpstat and I think you'll find out that this display shows cpu sets! In a multiple cpu machine, CPU's can be grouped into "sets". Unless there is a defination to group otherwise, a dual processor machine will indicate only one "set".

Create a new profile exclusively for the 4.0 beta version and create a desktop shortcut with -P "profile" appended to the target to launch that profile.
