New 27" Imac with no screen dimmer slider and not responding to F1

I hope someone has the answer to this. =) I just purchased the 27" Imac that was an open box buy from Best Buy. When I opened it, it had Yosemite installed on it. I went to adjust the screen brightness (under the preferences pane) and there is no slider! I then tried the F1 & F2 keys.....nothing. All the other function keys work, but not those two. I called Apple and was told I needed to take everything off and reinstall then upgrade to Yosemite. Fine....nothing. I made an appointment to take it into the Genius Bar and they couldn't figure it out either. I took it back to Best Buy and into the Geek Squad (then had to send it somewhere). They told me something I can hardly believe. They said the slider bar and function keys work in Mavericks (which I guess is what it came with) but once you upgrade to Yosemite, the slider and keys become unusable. So does this mean I can't ever upgrade? Does anyone have a fix for this??? Please, please help me. Thanks in advance.

Thank you for your advice.
I will use if the IMac will not we under warranty but since now it is still covered it is Apple's problem to fix it. Anyhow this is now the smallest problem since the Mac is not working at all.
Now the problem is that I'm not in Korea until 20th of July and I will like to make the arrangements that my Imac will be taken for service asap. Unfortunately beside the phone number for service support that was not working before my departure and the e-mail address of one Apple worker (but not from support team) that didn't reply to my last e-mail I have no other contacts.
I don't know where to send a complain or service request.
I still hope that an Apple employee will read my post and will take action or that one member of the forum with the same problems in the past will provide me some hints about the Apple support service.
Until then I try to enjoy my holiday.
Tank you again.

HT201406 When I open a web page the screen gets dark and not responding

Screen ges dark and non- responding can't get out of it frozen

Try clearing Safari's cache : Settings > Safari > Clear Cookies And Data (Clear Cache on iOS 4) and also Clear History
If that doesn't work then try closing Safari via the taskbar and then re-open it : from the home screen (i.e. not with Safari 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Safari app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
A third option is a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

Apple will exchange your iPod for a refurbished one for $199 for 64 GB 4G and $99 for the other 4Gs. They do not fix yours.

My iPad screen is black and not responding, I've tried everything on the help page, but can't restore or backup as it has a passcode. how do i disable if i can't turn it on? thanks

My ipad screen is blank, ive tried to do the suggested help pages, of back up and restore, but the ipad has a passcode, which i cant type in a the screen is black. how do i overide?
thanks liz

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430

‘iPad is disabled’ fix without resetting using iTunes
Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
2. Open iTunes with the iPad disconnected.
3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
5. Click ‘Setup as new iPad’ and then click restore.
6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
8. The first stage in the restore process unlocks the iPad, you are basically just canceling out the restore process as soon as it reactivates the iPad.
If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.

Try it and good luck. You have nothing more to lose if it doesn't work for you.

HT1212 My fully charged iPhone screen is black and not responding. what can I do to get it to work again? I have never syncd on iTunes. I connected to my laptop and iTunes app displays error msg saying phone is locked and unlock phone to connect.

My fully charged iPhone has a black screen and is not responding but has Siri and sound. I connected to laptop and iTunes gives error msg indicating phone is locked and I to enter passcode. but I can't enter the passcode because the screen is black. I have never syncd with iTunes. What can I do to get my phone back?

First thing to try is to reset your device. Press and hold the Home and Sleep buttons simultaneously until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.

After the recent update I am having issues with Flash based games freezing and not responding.

After the recent update I am having issues with flash based programs not running or loading correctly. The programs will not load or take an extremely long time to load compared to jsut a few days ago. This happens across the board on anything flash based. Also, once they do load they will freeze, stop responding or need to be constantly refreshed to come back alive which is short lived at best. I went thru the help and did all the file deleting, cache clearing, disabling hardware acceleration, removing then reinstalling flash, and even removing and reinstalling my browsers. None of this has helped at all. I am using Chrome and it is up to date and I checked my Flash player and it is up to date. I am running windows 7 64bit.

Here's what you're up against guys,
Adobe writes the base code for Flash Player, and then hands it off to Google, who adapt it to a PPAPI plug-in (it's NPAPI when Adobe writes it). It's then "PepperFlash" and Google embeds it in their Chrome browser. While Google is pushing a "webwide" move to PPAPI Flash Content, a reinvention of the wheel so to speak, not everyone "got the memo", and Google is slowly making it so that PepperFlash will block NPAPI Flash content from running properly, and you have to disable PepperFlash to force the NPAPI plug-in to work, which sometimes fixes it, sometimes not. I have a feeling this is only going to get worse. HTML5 will eventually resolve the video end but game developers need to come up with something that won't require a plug-in.
And to the first post: Since PepperFlash is embedded in Chrome by Google, you can uninstall and reinstall Flash Player from here until your hard drive literally seizes up.... guess what? It has NO EFFECT at all on the PepperFlash plug-in in Chrome because it's a separate file in a separate folder and the uninstaller & installers don't have anything to do with it.

Dear Nokia,

Hi abdelmagidosama,
Welcome to the forum! Could be that the memory is low. Firstly clear the browser cache:
Browser > Options (right bottom corner) > Settings > Privacy > Clear privacy data.
Go to Nokia Store application > Options > Account > Settings > Installation preferences > Select something else than Phone memory. After this delete and reinstall possible application you have installed to phone memory.
If the issue persists, then make a back up with Nokia Suite. Type in *#7370# = hard reset, phone memory will be wiped. Restore back up. If not helping, try to do the back up without settings.
You can also reinstall the software. The process is the same when updating, but at the end select "reinstall".
Hope you get the phone working normally again!

Has anyone used the new 5K imac with AE CC and is it a big improvment speed wise or not?

I am thinking about getting the 5K imac with the i7 4.4 GHz quad-core and AMD Radeon R9 M295X 4GB GDDR5, but my big concern is that the video card is not Nvidia and does not use cuda core.
I currently have a late 2012 imac with the 3.4 Intel Core i7 and a Nvidia GeFroce GTX 680MX 2048 MB and sometimes it is very slow when working with a lot of effects or layers.
1. If you have any experience with the 5K imac, please let me know how you like it?
2. Was Apple going to the AMD video card a good or bad thing?
3. Do you think I would benefit any speed gain with the new 5K imac and by what percentage.

The AMD video card is not a good hardware selection with the current media content creation software. Open CL is still lagging behind CUDA in performance and the CPU's did not change with the new Imac. So basically it's a new Imac with a updated video card and 5K screen. Not something I would suggest for Adobe if you already have an Nvidia solution.

IF I BUY THE NEW 24" IMAC WITH A 3GB AIRPORT DO I NEED TO GET AN AIRPORT EXPRESS?

IF I BUY THE NEW 24" IMAC WITH A 3GB AIRPORT DO I NEED TO GET AN AIRPORT EXPRESS?

All Macs have a built in Airport card. You can connect to the internet either using an ethernet cable back to your modem/router, or by wi-fi. If you already have a modem/router which provides a wifi network you don't need anything in addition to the Mac. If you don't have a router providing a wifi network then you will need one - it doesn't have to be an Apple one though they are probably the most suitable.
You say 'a 3GB Airport' - do you mean a Time Capsule? - that is a router providing wifi.

Of course! Here ya go
For the record, I did create a new project with only two slides to try and duplicate the issue. I had the same problem. I unchecked the Mouse Click Sound check box, republished and the slide auto advanced. I'm wondering if a default sound file was somehow moved or deleted? I discussed uninstalling and reinstalling C7 onto my laptop, but that's a frustrating solution haha

I am going to load windows 7 via Boot Camp for other reasns. After that is done, and even with an external Blu Ray player, is it still not possible to play Blu ray movies?
Thanks for your consideration.....
