HT5219 I have a macbook air (mid 2012) and a thunderbolt display. Do I absolutely need to connect the power supply together with the thunderbolt cable ? I found that the screen won't wake up if only the thunderbolt connection is plugged.

I have a macbook air (mid 2012) and a thunderbolt display (27'').
Do I absolutely need to connect the power supply together with the thunderbolt cable ?
I found that the screen won't wake up if only the thunderbolt connection is plugged. Is this normal ?

I just got my ATD and late 2011 MBP up and running. I've not tried running without the power adapter from the ATD plugged in, but I just tried and didn't have any problems with the display not waking. You may want to take your query to the ATD forum - https://discussions.apple.com/community/peripherals/thunderbolt_display - perhaps someone there has experienced a similar issue.
Good luck,

MacBook Air (mid 2012) and AirPlay

I have a MacBook Air (mid 2012) and just purchased the Apple TV. I tried to connect my laptop to Apple TV but don't have the option. Is AirPlay only available on Mountain Lion?

Turn on home sharing in Itunes.
You would need an upgrade to Mountain Lion to be able to utilitize AirPlay with your Apple TV........UNLESS YOU USE BEAMER APP
Something to STRONGLY consider is the APP called BEAMER
free trial
http://beamer-app.com/
one of the most useful APPS ever created (outside of productivity APPS, that is).
Make sure your Mac can run Mountain Lion (which you can on your 2012 AIR) > System requirements for OS X Mountain Lion
Moutain Lion can be purchased from the Mac App Store - OS X Mountain Lion
Lion OS X v10.7
Mountain Lion OS X v10.8

HT3986 Where can i download the driver for my network card? i have a macbook pro mid 2012, and are using windows 7 ultimate

Where can i download the driver for my network card? i have a macbook pro mid 2012, and are using windows 7 ultimate

uhm hey guys,
idk where else to get help so ima try here,
i got windows 8 installed with bootcamp on my macbook pro late 2010 (5, 5) and theres no sound coming out of it, so i installed an nvidia audio driver (idk, it could be the incorrect one) but i have nvidia GeForce 320 on my macbook.
do you know what i should install ?
but when i go onto my osx the sound is fine, so i figured im missing something on windows 8
Orrrr could i just go out and get parallels and hope it doesn't get the same problems?

AirDrop doesn'n work between Macbook Pro Mid 2012 and Mac Book Air mid 2013 using both Yosemite

Can't search other devices using AirDrop between between Macbook Pro Mid 2012 and Mac Book Air mid 2013 using both Yosemite...
And trying with MBP late 2011 can't connect either

I have a new MacBook Pro Mid 2012 and it goes into deep sleep when I disconnect if from AC power.

I have a new 13" MacBook Pro mid 2012 and it goes into deep sleep when it is disconnected from AC power. I have to press the power button to wake it up. Is this a known issue or is there something wrong with the MacBook Pro?

There are a few threads about this around. Its a known issue for 2012 non retina users, not sure about Apple. It should not work this way and Apple has not put out an update to fix it yet. Check out these threads for some workarounds. I think I saw if you reinstall and don't update one of the updates you get normal functionality back. Otherwise there are some terminal changes you can make to make it operate mostly normally. I made some changes in terminal.

1. I didn't cycle it too much! see I have 400 cycles and counting.
2. I use my computer all day long and charge it until i get to around 30-40% of charge. I use it all morning on battery charge and at noon switch to plug it on charger. BTW I leave it all night charging it so that next day I have full charge on my macbook pro so i can use at school.
3. I used to play GTA SAN ANDREAS on it but usually while charging due to the game sucking all my battery charge
PS: The battery should last up to 1000 cycles according to my model.
Wrong, the battery CAN last UP TO 1000 cycles.
Ive seen well treated battery get over 1300 cycles before the chemistry is ruined.
I can, if so inclined, easily destroy a lithium battery within 300~400 'cycles'   (cycle count is not what ruins a battery within 1 to 3 years...., its short term abuse).
I use it all morning on battery charge and at noon switch to plug it on charger.
You didnt answer the ONLY important question............do you often drain the battery very low?
Cycle counts mean almost nothing .........there is a huge myth about charging cycles. (see below)
Proper understanding of a battery charge cycle
A charge cycle means using all of the battery’s power, whether that is at once, or over several shorter battery discharges and recharges.
Two examples for clarification:
As a first example, where one fully charged battery is discharged down to 10%, then fully recharged, then using 10% of that full charge, this counts as 1 cycle since the total of both discharges is 100% of a full charge of use.
In the second example, where one fully charged battery is discharged down to 40%, then fully recharged, then using 40% of that full charge, this also counts as 1 cycle since the total of both discharges is 100% of a full charge of use.
While both examples are that of a single charge cycle, the first example is more aggressive against the lithium battery chemistry than is the second example. In short, collective overall gentle shallow or mid-range draining of your lithium battery is a better use condition than is the first example of deep-draining of the battery. While both are quantitatively identical as a single charging cycle, they are wholly different qualitatively on the battery chemistry, which is directly related to its ultimate longevity and health.
In short, it is the near and mid-term life of the battery as relates to its proper care (or lack thereof) that is to be looked after.
Priorities in order of decreasing importance for battery care are:
1. Avoiding deep discharges of the battery.
2. Avoiding having your battery constantly on charge or on charge and in sleep mode.
3. When playing graphics intense games, use your notebook plugged in when possible.
4. Reduction of battery cycles by plugging into power when on the go, or when accessible.
A person who has, for example, 300 charge cycles on their battery and is recharging at say 40% remaining of a 100% charge has a better battery condition state than, say, another person who has 300 charge cycles on their battery and is recharging at say 10-15% remaining on a 100% charge. DoD (depth of discharge) is vitally important on the wear and tear on your Macbook’s battery, much more so than is the counting of charge cycles. There is no set “mile” or wear from a charge cycle in specific. Frequent high depth of discharge rates (draining the battery very low) on a Lithium battery will greatly hasten the lowering of maximum battery capacity.
Understand that a charge cycle is a general parameter of use, but is not directly related to the short-term or mid-term abuse of the battery, which can rapidly hasten a shorter lifespan, regardless of what the actual cycle count on the battery indicates.
Proper considerations for near-term care of the battery is of utmost importance. Abuse of the battery is entirely avoidable, long-term eventual old age deterioration of the battery is entirely unavoidable.
Apple’s adaptive charging system mitigates much potential for accidental battery misuse or abuse; however it is still readily possible to abuse the battery and thereby affect battery health.

MacBook Pro Mid-2012 A1322 Battery

I have the Mid-2012 13inch MacBook Pro. The battery stopped charging, and the icon shows a Condition: Replace Now warning. The Apple Diagnostics shows the BAT/40000 code, so i want to order a battery. What I want to ask, is that are all original A1322 batteries the same? Is the same Battery used for the 2010, 2011 and 2012 models?

Purchasing a battery for a MBP from a third party source is like playing Russian roulette. Too often the battery does not perform properly and lasts a short time. These forums are full of such tales of woe.
I strongly urge you to get a battery at an Apple store. It will work and have a warranty.
Ciao.

Issues with MacBook Pro mid 2012 and SSD data 3

I installed a Samsung SSD in my macbook pro model A1278, it work very well since yesterday; maverick 10.9.2 run very very slow and it have a lot of lag. And so ai provide to reinstall the native HDD and it run very well. I decided to buy another SSD of OCZ, the previous was Samsung 830, and the system didn't recognise the ssd, but if i link it with usb it work. Anyone have the same problem?

Thank you for your reply :),
I verified multiple times to ensure that the MBP-R and the ATV2 were connected to the same wifi. That's all that would be required with my network set up since there are no configured sub-networks. All of the devices connected can see each-other. I also verified this by checking in the router. Sure enough, the ATV2 is listed with all of the other devices.
There were other problems related to Internet content with the ATV2 when I shipped it in for repairs under warranty. It was constantly disconnecting and reconnecting, and no matter what, it wouldn't remember any settings. I noticed these defects after I asked this question. I suspect that, because there has been some horrible weather and lots of power surges here, that it became damaged from a surge. This was not plugged into a surge protector like everything else, so I brought that on upon myself unfortunately.

Macbook pro mid 2012 and the airplay feature does not come up. it comes up in itunes but not on the menu bar or in the displays settings. What can i do?

I just bought my macbook pro 2 weeks ago. I am new to apple so it is pretty much greek to me at this point but I have been able to figure out or google most of my questions. I have found a million posts about the Airplay feature for mirrioring and most of them are the same issue having a mac that is pre 2011. There should be no reason I would not have the Airplay option on my system.. I have done the updates avaliable for both the mac and the AppleTV unit, which is a Gen 2 or 3, Also brand new as of 2 weeks ago. Does anyone know what else I can do or is this something I will have to take in the the Apple Store to fix?

You're running Lion, and Mirroring is in Mountain Lion. http://www.apple.com/osx/uptodate

How to maintain a macbook pro mid 2012's battery life

Hello,
I know that there are a lot of past posts of this, but they still leave me unanswered. Being a recent windows user, I don't know everything there is to know about macs, however the one thing I do know is how expensive they are, so I want to keep everything in tact for as long as possible.
One of the key things I have realised from these discussions is that people are saying it's bad to leave a mac charging, it's bad to fully decharge a mac, and it also seems alright to not charge it fully or decharge it fully before charging. These were all kind of confusing to me as I thought to keep a battery healthy, you had to completelly drain it before charging it, charge it fully whenever you charge it, and it didn't hurt to keep it charging constantly.
Now for anyone who doesn't want to read all thet above, the key things I want to know are:
How to keep the battery healthy
Will fully decharging it affect it
What happens if I don't fully decharge before charging/ what happens if I don't charge it all the way
What happens if I leave it charging constantly
And if I am charging it on and off at school, what will happen (i.e. one period I charge it 20%, then unplug it and then charge it another 20% the next period)
Thanks for all your answers in advance, and cheers for reading all this. I hope you can clear me up .

FALSE information. You may leave your MBP attached to the charger as much as you want. It cannot over charge. Avoid draining the battery completely. That will shorten battery life.
I keep mine charging all the time but about one per mont will use it with just the batter yo about the 40% charge level.
And if I am charging it on and off at school, what will happen (i.e. one period I charge it 20%, then unplug it and then charge it another 20% the next period)
You sometimes have to deal with realities. When Ac is available, use it, but it will not be so at all time. It will not have a great adverse affect on the battery.
Here are some articles that you should read that will fill in the details:

I am using a Macbook Air mid 2012 and an apple application "Mail". With only one email account (Yahoo), everything works perfectly. But the problem started when I added GMAIL account. Now it keeps on asking for my password for gmail and keychain.

With only Yahoo account in my Macbook Air "Mail", everything works perfectly. Problem started when I added my Gmail account. It keeps on asking my account and keychain passwords. And all my accounts always works offline.

It sounds like you may need to go into Mail>Preferences>Accounts and Complete setting up you Gmail account. It may not be finished being setup. For instance, note the line below to be selected from the drop down list in "Outgoing Mail Server (SMTP", then "Edit SMTP Server List":
Hope this helps

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.

Can Apple replace my macbook pro (mid 2012) retina's battery if I think that the battery health has gone bad/in need of and renewal?

Can Apple replace my macbook pro (mid 2012) retina's battery if I think that the battery health has gone bad/in need of and renewal???
I've had my Macbook for about 11 months now and i use it every day; its gone though about 420 cycles of charging and using the power, and i noticed the battrey preformance has decreased (as expected). The problem isn't sevear yet but it would comfort me knowing that i could replace the battery in the near future
Please contact me or answer the question if you know anything about this!

No only if they think under warranty/AppleCare, but your likely able to pay for a new battery if they have them, which they might not yet since it's such a new machine still.
BTW, I have a Early 2011 17" MBP, 27 months old, charges to 97% and has only 14 cycles.

Hey everybody. Do you know if i can run os x server on macbook pro mid 2012 with i5 2.5 GH, 4Gb RAM and OS X 10.8.4?
