If you read the instructions for installing a firmware update you would then know the behavior was normal.

My iPad 3 is not charging on my macbook pro mid-2012. It was working yesterday and it is not working now, and I'm trying to transfer files between them. How do I charge my iPad with my macbook without having to be a completely new computer?

I am trying to transfer files between my ipad 3 and my macbook pro mid-2012 and they will just not connect. I connected them yesterday and it worked fine. And i can not air drop these files into my ipad it has to be done through itunes. And i can not afford to buy a new computer. How do i get these two to connect without having to buy a completely new computer?

Computer USB ports, regardless of the computer maker, have a relatively low power output and thus are not good chargers. They will charge but it takes a long time. You should be charging your iPad from wall power, or a more powerful source like an in-car charger.
Buying another computer will not change that.

Macbook Pro, bought 2012, takes a very long time to start up/restart (5 mins). How do I fix this?

My Macbook Pro, bought 2012, takes a very long time to start up/restart (5 mins) every single time I have shut it down. I try not to shut it down at all now because once or twice, I have got a grey screen, and then nothing. I've held down the power button to shut down again and restart How do I fix all this?

Start up with your built-in Recovery disk by holding down the Command and R keys when starting. Open Disk Utility from there and use it to REPAIR your disk (you've already verified it and it came up with errors).
With any luck, your problems will be solved. While I was there, I would also repair permissions.
Good luck,

My Macbook Pro (Mid-2012) won't connect to an external display using my MiniDP to VGA Cable.

I'm on a Macbook Pro (Mid-2012) on Mac OS X 10.8.3 (currently downloading the update to 8.4). When I plug in my Mini Displayport to VGA adapter to my Mac, the screen flickers blue for a second and the Display Settings window detects the other monitor and allows me to rearrange the screen, but it does not project anything onto the other monitor. However, I tried connecting an Apple Thunderbolt Monitor to this computer today, and it worked. This wasn't a problem before, as I was able to connect this Mac to other LCD projects before. Furthermore, I don't think it's an issue with the adapter either because it's relatively new. I also tried plugging in the adapter of another Mac (which was working fine) into my Mac, but it didn't work either.
Here's what I've tried:
1. Restarting the computer with everything plugged in
2. Pressing Command + F1 when it's plugged
Any advice would be helpful!

MacBook Pro(Mid 2012) Can't connect to my Dynex TV with mini display port to VGA adapter

I have a MacBook Pro(Mid 2012, running OS X 10.9.4) and I recently just bought a mini display port to VGA adapter so I could hook it up to my dynex TV but when I connect everything my TV says no signal. Do I need to do something in settings?

How do I enable TDM?
Make sure both computers are turned on and awake.
Connect a male-to-male Mini DisplayPort or ThunderBolt cable to each computer.
Press Command-F2 on the keyboard of the iMac being used as a display to enable TDM.
Note: In Keyboard System Preferences, if the checkbox is enabled for "Use all F1, F2, etc. keys as standard functions keys," the key combination changes to Command-Fn-F2.

I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

I want to remove the monitor from my 17" Macbook Pro 2008 to use as an external for my Macbook Pro 15" 2012. How can I convert lvds to Thunderbolt and power the monitor?

It's almost impossible. The new iMacs have a Target Display Mode, but it's built to do that. Without ripping your screen out, finding an acceptable power supply, frame, and whatever electronics to convert a Thunderbolt signal to the screen, the cost will be much larger than buying a cheaper HiDef monitor that runs with an HDMI to Thunderbolt cable to your MacBook 15. In fact, you can sell your 17" MBP for a lot of money, unless it's broken or something, buying you a really sweet monitor.
By the way, I found your answer by searching this forum. I would suggest using the search function here in the futuere.

Can I use my macbook pro mid 2012 as an external display using thunderbolt port

Hi,
I want to use my macbook pro (mid 2012) screen as an external display for a raspberry pi using a HDMI to Thunderbolt cable, via the thunderbolt port on the macbook pro. Would this be possible? Can the macbook pro's thunder bolt port act as an input and is any additional software required?
I look forward to hearing from you.
Thanks in advance!

Welcome to Apple Support Communities
You are referring to Target Display mode. Target Display mode can only be used in 27-inch iMacs and iMacs with Thunderbolt, not MacBooks Pro > http://support.apple.com/kb/PH11302
Unfortunately, you can't use the MacBook Pro as a display. It doesn't support the monitor mode

Macbook pro mid-2012 13" has very slow disk access

Until 3 days ago my macbook pro mid-2012 13" running OX 10.8.3 was running fine. Then, it showed very slow response anytime it had to access the hard disk. After doing the usual checks and disk first aid repairs to no avail, I booted from my external disk with an older copy of my hard disk and everything then worked as normal, except when I accessed the internal hard disk, then it crawled once again (spinning beach ball, took many seconds just to open a finder window and then several minutes to display the contents). I ran the Apple Hardware Tests and it said everything was fine, even though it tooks several minutes before the test would actually start. I also ran the program BlackMagic Speed Disk to find out if the disk was having transfer speed problems and it showed a respectible transfer rate (60MB/s), not great but not like the 0.3MB/s I was getting when I tried to back up the internal disk. I was using Carbon Copy Cloner to try to back up the internal disk but had to give up since at 0.3MB/s, it would take days to back up the 250GB on the disk. I found on the web that using "restore" in Disk Utility, I could do a disk copy without the file by file copy which allowed me to back up my disk in "only" 6 hours. Booting from my newly made copy on an external disk worked fine and ran at nearly normal speed (slightly slower since it was an external disk running through USB2). As a final attempt to prove this was a disk problem, I erased the internal disk and reinstalled OSX 10.8. I am still waiting for this install to finish, it has been 5 hours although the progress bar said it should be done in 20 minutes. This was fairly convincing evidence that it is not a software or settings problem. However, all my web searches could find no other case of a problem like mine. I presume I have a failed hard disk but as all the diagnostic programs say it is working fine, I was hesitating to bring it in without hard diagnostic evidence. If anyone knows what might be the problem, it would be much appreciated to hear from you.

It should not take 5 hours to install Mac OS X. There is something wrong with the disk. Try reformatting where you do a wipe of the drive (an select the option to write zeros which will remap bad sectors). Then try to install MAc OS X.
I got this information from here:
http://reviews.cnet.com/8301-13727_7-20064489-263.html
Back up your data.
Use Time Machine or a system cloning utility to create a full and restorable backup of your data. If you suspect bad blocks, then when cloning you might consider not using a "block-level" copy process, since this will likely run into problems.
Boot to the utilities DVD.
If you have a boot DVD for a tool like Drive Genius or another drive utility, then boot to that; if not, use your OS X installation DVD (once you select your language, open Disk Utility from the Utilities menu).
Format the drive.
Using your selected utility, format the drive and check for bad blocks. If you are using Disk Utility, click the Erase tab, click the Options button, and then select the option to write zeros to the disk (you do not need to do multipass erase options, as this will provide no additional benefit for managing bad blocks). Writing to zeros may take a couple of hours depending on the size of the drive, but when done the drive will have remapped any blocks that were not reliably read.
Restore the OS installation.
If you have used Time Machine to create your backup, boot to your OS X installation DVD (if you are not using Disk Utility) and use the option in the Utilities menu to restore from backup. Attach your Time Machine drive and then proceed with the restoration, selecting the newest backup as the one to restore to your system. If you have used a system cloning tool, then attach the cloned drive and boot off of it (hold the Option key at start-up to select it from the boot menu). When you are booted to the cloned drive, run your cloning utility to copy the installation back to the computer's main boot drive.An optional approach here is to perform a full reinstallation of the OS from your installation DVD, and then migrate your data, applications, and settings from either the clone or the Time Machine backups using Apple's Migration Assistant.

MacBook Pro mid 2012 15" - one RAM slot gone bad

Hi,
Has anyone ever had the issue with not working RAM slot? My MacBook Pro mid 2012 (non-retina) suddenly froze and after restart was beeping three times every few seconds. I found out that the beeping signals bad RAM. Bought new chips, and the problem still exists. My mac can now run on one slot with 4GB RAM.
I did check the placement of the chips in the slots, i also checked one slot at a time, and one of them has gone broken.
Any ideas on how to make it run again? or if it is possible to replace the slots?

The Apple-accepted cure for a dead RAM slot is a new logic board. Unless you ahve AppleCare, that will be an expensive fix.
An Apple service option is the "depot repair." Instead of working on your computer in the Apple Store, they send it to a centralized refurbishment facility where they fix anything they find wrong (except for cosmetic damage and damage from abuse like dropping) for a flat fee of a little over US$300. That is between 30 and 40 percent of the parts and labor charges if Apple installs a new board in an Apple Store. Sometimes they will install an new battery at the depot without increasing the flat fee.
The downside is that it takes about a week; for that level of cost savings, I could do without my computer for a week.
So take it to Apple and ask about a depot repair.
A low-tech and low-cost option is to expand on what you are doing now--using one slot. Although the official RAM limit on your model is 8GB RAM (two 4GB models), your model can actually handle a total of 16GB (two 8GB modules. You can ignore the dead slot and put an 8GB module in the good slot. My 2012 MBP has 8GB RAM and is completely happy running Mavericks.
Be sure to ONLY get the RAM from an Mac-savvy vendor. For over a decade I've bought all our Mac RAM from one supplier. This is their page for an 8GB module for your MBP model:
http://eshop.macsales.com/item/OWC/1600DDR3S8GB/
I would also trust Crucial on this one. For a change they recognize that your model can use more RAM than stated in Apple's outdated specs:

Macbook Pro (Mid 2012) Startup Time Increased

Hi everyone,
I have a Macbook Pro (Mid 2012) non-retina model. I have an upgraded SSD (Crucial MX100). The startup time from switching on to the login screen is usually around five seconds but since this morning the time has increased to around 40 seconds. When the power button is pressed, the tone sounds and the screen lights up but it takes quite a while for the apple logo to appear. I haven't added or removed anything or changed any settings since before this happened. There doesn't seem to be any changes to the performance of the computer once it has started up, or the time taken from the password entered for the bar to load (Yosemite).
My hard drive cable once broke and I had it replaced at an Apple store (if that means anything to anyone). If anyone could give me any possible explanations or advise on how I can return the boot up time to the normal time.
Thanks,
Ben

Macbook pro mid-2012 GPU-panic

Hi, my Macbook Pro mid-2012 has recently started rebooting sporadically. After some investigation I found out that it is caused by GPU Panic which happens EVERY TIME when discrete GPU (NVidia 650M) is enabled and its temperature goes over 64-65 degrees (Celsius, according to iStat).
It seems it started to happen after one of the OS updates.
Did you faced this issue? Is it software or hardware related? Are there any workarounds/fixes?
Now I am using gfxCardStatus to use Integrated GPU only, but it makes not possible using any 3D-games on this laptop.
Thanks,
Nikolay

Are you running any anti-virus or internet security software? Any cleaning, tune-up, "keeper," or optimization apps that did not come preinstalled?
Are you set up to do torrent downloading?
Are you using backup software other than Time Machine, like that which comes bundled with a external hard drive?
Are you using an online backup serviceother than iCloud (Carbonite; MS OneDrive; Google Drive)?
Those can run up the internal temps.

Migration Assistant can't find External HD on MacBook Pro Mid-2012

Hi, I have a MacBook Pro Mid-2012 running OS X Mountain Lion 10.8.2 and I am trying to use Migration Assistant to transfer Time Machine backups that are on my external hard drive, that I backed up from my old MacBook Mid-2010. The problem I am having is that Migration Assistant can't find my external hard drive. My MacBook Pro can find it when I plug it in (I see it in Finder), but Migration Assistant can't. Can anyone help or should I go to the Apple Store? I need help with this problem as soon as possible.
Thanks in advance,
- Daniel 

Since no one replied I figured out how to do it myself.
1.) First I plugged in my external hard drive with my Time Machine backups on them, then I opened Finder and click on my external hard drive under devices.
2.) Next I clicked on and opened the folder named "Backups.backupdb"
3.) Once inside that folder I could see folders with the backups from Time Machine and all of the folders names were the date I backed up that backup. I clicked and opended the lastest backup folder.
4.) Inside that folder, I clicked and opened the folder named "Macintosh HD"
5.) Inside that folder, I clicked and opended the folder named "Users"
6.) Inside that folder, I clicked and opended the folder named "Daniel" which was my Username on my previous Mac.
7.) Finally I could see and access all my folders from my Time Machine backups from my previous Mac.
Keep in mind this is only helpful if you are trying to access old backups (backed up from another Mac) on a new or different Mac. (Sorry for the blurry images)
Hope this somehow helps someone else,

Macbook pro mid 2012 no retina performance drop after efi

Hi, mi macbook pro mid 2012 no retina after efi update the performance are too slow, thats is the same problem with retina, please fix it, in osx mountain lyon the aplications that used every daywith video is poor, in bootcamp with games is the same problem, the cpu clock drops from3.3 ghz to 1.2 ghz or more. Waiting for a mew efi update bescause my mac is the same that a macbook air

No Apple hasn't officially stated anything about this issue. After I updated to EFI Update 2.0 I noticed the issues and started doing my research and found people in the Macrumors forums having the same problems and eventually I was reading that users that didn't update yet weren't seeing the update in their updates meaning Apple pulled the update from the servers. Other users reported after calling Applecare that they were aware of the issue.

Can anyone recommend a portable USB 3.0 drive with hardware encryption, compatible with OSX and Windows 7. I need it for my MacBook Pro 13", 2012, running Mountain Lion

Can anyone recommend a portable USB 3.0 drive with hardware encryption, compatible with OSX Mountain Lion and Windows 7. I need it for my MacBook Pro 13”, 2012, running Mountain Lion & Windows 7 Ultimate - BootCamp. I’ve heard that the Buffalo MiniStation Encryption does not work with OSX, is that true..? I'd like it to work with both operating systems, using the built in hardware encryption. Thanks
