I have a Macbook Pro late 2012 model with intel processor and 4G of RAM. I upgraded to Yosemite and now my system is so slow. I do not have a backup to revert to because of insufficient space. I have ordered a 1T external drive to do a backup now. What can I do to improve my system performance? Do I need to upgrade RAM or do I have to reinstall Mtn Lion?

I recently attempted to re-install Mountain Lion on my MacBook Pro late 2012 model and the internet recovery is failing.

I recently attempted to re-install Mountain Lion on my MacBook Pro late 2012 model and the internet recovery is failing. I have absolutely no clue what to do here. Any help is greatly appreciated. Thank you.
- Currently if I boot it up there is a flashing folder icon with a question mark in it. I am assuming this means there is no OS because I wiped the SSD and tried to reinstall Mountain Lion
- When I hold Command+R, it prompts me to Choose Network... the problem with this is the wifi constantly is disconnecting. The Retina 2012 does not have an ethernet port so i have considered buying the attachment then returning when done.
Once again Thank you in advance.
Best.

There is nothing to do if you don't have a reliable Internet connection unless you have a copy of the Mountain Lion installer application from when you first installed it.
Install or Reinstall Mavericks or Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.

Factory resetting a macbook pro 13" 2012 model with 10.9.4 OS running

Hi. I have a macbook pro 13" 2012 model with 10.9.4 OS running. I want to restore it back to factory settings. I tried the command R at the boot but after downloading the os through internet, it does not allow me to install it. The error is shown that i have a newer os and cannot install it to the older one. So is there any other way to do this?
Also when i use the option key at boot up it shows Recovery 10.9 and when i click on that the mac shuts down, every time.
Thanks.

Boot into Internet Recovery mode, ⌘⌥+R, select Disk Utility, and erase and reformat the HD, quit Disk Utility, and restore the OS. That should put the OS the machine shipped with on the HD.

Best monitor for MacBook Pro (Late 2012)

After searching Apple's knowledge base (reference: Using 4K displays and Ultra HD TVs with Mac computers - Apple Support), it appears that MacBook Pro (Late 2012 model) does not support 4K monitors, correct?
If this is the case, what's the best monitor (resolution and pricepoint) I can get for this model? Should I just try to find an old refurbished 27" Thunderbolt Display?
My MBPr runs a 2.9Ghz Intel Core i7 w/8GB RAM and OS X v10.9.5.
Thanks,

A Dell ultra Sharp would be a good buy. Depending on what size you want:

Otherwise, if you don't mind spending the money, and not worried about not using the monitor to its fullest this BENQ is an excellent monitor

Using a macbook pro (late 2012) as primary desktop recommended?

I own a macbook pro Late 2012 edition and I am thinking about connecting it to an external monitor and using it as my primary desktop. Is this recommended? I am afraid that it will harm my macbook..especially the battery. Any insight would be appreciated.

If you use an external keyboard, USB or BT (as a desktop computer, you could use USB
and use a powered USB hub for printer, mouse, keyboard, etc and to import from devices
such as cameras, etc) and either get a stand to keep the MacBook Pro on edge out of
the way with the lid closed, or use it on a different stand to keep it up off the desk so air
can flow around it, with display lid open, for maximum cooling & extended/mirror desktop
use of the integrated display along with an external.
The battery should be used on occasion and not overly 'cycled' since it likely is one good
for up to 1,000 cycles of discharge & recharge; but never let it go completely flat or that
would damage its ability to carry a full charge. If I'm not mistaken that model is one with
an integrated or hidden battery behind the bottom plate, so it can't be removed and run;
but then if you did remove a laptop battery, it likely would cause the processor to reduce
speed and be less than optimal specification when you needed it for higher function tasks.
There are articles in Apple Support database on how to care for a portable Mac battery
and also some may be dated in that older models are suggested to be Calibrated on
occasion and the newest batteries (such as those in Retina models) are different. If you
have a MacBook/Pro with non-Retina display, check the support articles to see if that
model, with a built-in SuperDrive, could benefit form Calibration of the battery.

It is a good idea to get a spare power adapter of the correct model for your Mac.
I see there are some that are exact replacement on occasion at OWC macsales.
While in use as a desktop replacement, the computer may work better if you use
USB peripherals as the BlueTooth and other accessories would see less wear;
however that may be subject to a bias against using the built-in items so they
would not have a chance to wear out. Like the internal keyboard, for example.
A USB keyboard works in situations where the BlueTooth may not, and also
is easy to replace, where the built-in one is not easy, nor inexpensive.
Expect to replace the battery before the approximate cycle life is reached,
though it may be possible to exceed 1,000 cycles as noted by some who
have said they did; however you can't be sure how they arrived there. A
matter of use-patterns and careful consideration on what the portable does
in the course of a few years time could make a difference in battery life.
Yet some batteries can go bad without timely cycling and use. But do not
let the batteries go flat, recharge before they get too low so they don't see
any damaging discharge.
With the extended AppleCare plan, an option, the battery is covered for the
total duration of the extended plan. With a built-in battery, that is a fair deal
since the replacement, when covered, includes labor. Some models were
made in such a way as to allow a careful out-of-warranty battery replacement.
Check the online sources such as iFixit to see if after AppleCare, you would
even want to try to replace the internal battery. The AppleStore Genius could
do it for a slight fee over the cost of a replacement battery at that time.
With my (now older) Apple portable computers, I use a laptop stand, USB mouse
and keyboard, powered USB hub, wireless base station with Ethernet option,
both wired and wireless printing, & do not use an external display though I could.
That said, I use a Mini (Late 2005) G4 1.5GHz most of the time. My computers
stay on most of the time, and are allowed to sleep. They have some degree of
protection from power grid ill-effects through use of a power conditioning UPS
that can automatically switch when power goes up or down, and provides some
degree of run-time when the power goes Out. Not a whole bunch, though.
With an external display, and other accessories needed to use the Mac and to
shut it down when the power goes completely out, you may need to use more
than one UPS or uninterruptible power supply, but in some cases it has been
suggested in prior manufacturer publication, to not attach the UPS (whatever
brand) so they use the same wall socket; the excess power is expected to
surge or bypass the UPS and go to the Grounding wire. Be sure there is one.
Anyway, I have a few ideas and due to a few losses from trees hitting lines,
and outages lasting more than a week, with use of 'soft-power' generators,
my experience may vary as could my advice. Plan for the worst and hope...
Good luck & happy computing!

The article you cited refers to The Mac Pro, a 50lb silver tower -- not a notebook computer.
Everymac.com says:
2nd Display Support:
Dual/Mirroring*
2nd Max. Resolution:
2560x1600 (x2*)
Details:
*This model supports a simultaneous maximum resolution up to 2560x1600 on two external displays via Thunderbolt. Alternately, it can support a single display up to 2560x1600 via Thunderbolt and a single display up to 1920x1200 via HDMI. Although it can theoretically power all three external displays, as confirmed by a helpful reader, it runs too hot with three displays connected.
Also see: How many external displays can the Retina Display MacBook Pro models support? What is the maximum supported resolution of each? Are adapters required?
When using other than ThunderBolt displays, the ThunderBolt port is directly compatible with Mini DisplayPort, and can be forced into compatibility (with Single-Link DVI or HDMI up to 1920 wide) with a simple adapter.
To adapt to wider displays, an ACTIVE Dual-Link adapter is needed, about US$100.

My Macbook pro Mid 2012 Model Seems to be using too much RAM

Hello everybody, I recenlty bought a Macbook pro Mid 2012 Model and I absolutely fell in love with it! I use it everyday for school, work, and for my musical hobby.
I haven't had a single problem with it until recently, and it seems like the RAM memory is being all used up without me even running programs. This problem barely started rougly 2-3 weeks ago and it's becoming annoying. I do plan to upgrade the ram soon seeing as the extra RAM will help run my engineering software I'm going to be using.
Anywho I'm just looking for tips, suggestions or answers as to why this problem is occuring. Also heard from a fellow employee that Google Chrome can cause this problem with RAM and battery life as well.

Stop using Chrome for any number of reasons and stick to Safari. An aspect of OS X memory management is to take over as much memory as possible in order to better manage the memory, however, this does not mean you are running out of memory. You only run out of memory when you try to run too many applications concurrently given the amount of RAM you have. You will know when that happens because the computer will slow down, you will see the beachball a lot, everything you do takes forever, and the hard drive will be grinding away.
About OS X Memory Management and Usage
Using Activity Monitor to read System Memory & determine how much RAM is used
OS X Mavericks- About Activity Monitor
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.
Adding RAM only makes it possible to run more programs concurrently. It doesn't speed up the computer nor make games run faster. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent. It will improve the performance of applications that run mostly in RAM or when loading programs.

Is the bumbed MacBook pro the 2012 model?

Is the bumbed MacBook pro the 2012 model?

This isn't 2012, so no, it's not a 2012 model, it's a late 2011 model (which is what Apple probably officially calls it). Whether there will be other new models released next year, no one here can say.

I have a MacBook Pro late 2008 edition with 2 Gigs of RAM and running Mavericks. When trying to download Yosemite from the App Store it gives me an error message. Anyone has a similar problem?

All,
I thought it may be related to spaces in the path in which the script was called from. I tried having the ODBC command script in another directory but the same thing happens. It will give me the "CONFIGSYSDSN: Unable to create a data source for the 'Oracle in OraClient10g_home1' driver: Could not load the setup or translator library with error code -2147467259". As soon as the script is done running I can manually double click the script and it adds the DSN fine.
Thanks,

Is MAC Pro (late 2013) compatible with Intel E5 or E7 Series 10 core CPU

Is MAC Pro (late 2013) compatible with Intel E5 or E7 series 10 core CPU?

http://macperformanceguide.com/MacPro2013-CPU-upgrade.html
Someone did some testing and these Xeon processors scale differently, turbo-boost means it can put a core to sleep when it isn't needed and give more to the cores that are.
But, the number of apps that do use more than 8-core are in short supply.
Then there is the contention between cooling and whether the cpu or the twin GPUs get preference, OS X won't allow both to ask for full 100%.
We assume you know all there is about cpu scaling and usage and just need to see which ones are on Intel's list that are pin compatible and have the right thermal requirements and such.
Fall is always IDF and v3 of the E5

I changed my wireless broadband to a landline-base DSL wifi and it works like a charm. Sun was the culprit even you fiddle with its router and disable firewall, it won't work.
try changing yours too and let me know how it goes.

Macbook Pro (Late 2011 model issue)

I purchased my Macbook pro (late 2011 Model) a couple of months back, towards the end of last year. Staright after i had purchased it, and had got it delivered i experienced cracking and clicking noises coming from within the Hinge of the Macbook. And got it replaced for a brand new one as i was still within the 2 weeks prior to purchase, as the apple policy states i was eligible to get a new if i had any problems. So i did. And the brand new replacement macbook pro that i have NOW has the same problem. Ever since i got the other one replaced THIS ONE has the problem or rather much worse, Cracking and clicking noises everywhere whenever i handle the notebook or carry it there is cracking noises everywhere. Whenever i open and close the screen lid, UP or Down. There is loud clicking noises coming from inside, sounds like something is breaking. This is totally unacceptable. First macbook had issue, replaced it, And now replaced Macbook pro is much worse. Since i had it replaced i havent had time to come bring it in. It still bears the same preoblem and is getting worse!

You're just going to have to take it into your local Apple Store. They won't replace again but you're still within your one-year warranty so they will certainly repair. I have the same model and have not have any of the problems that you describe.

Clinton

SSD Upgrade MacBook Pro Mid 2012 (Model: 9,2)

Hey guys!
Well as some of you might already have read, I will upgrade the RAM of my MacBook Pro, and since I decided to do this, I tought that why maybe not do the SSD as well. I want to know which is the best option for an High Quality SSD for my MacBook Pro Mid 2012 (Intel Core i5 2.5 MHz, 4GB RAM (upgrading to 16GB). I've read that Crucial, but I want an SSD with more than 512 GB which is the amount my Mac came with in the default HD.
Thanks!
Later.

OWC offers a 960GB SSD with top reliability and storage capacity:

For a little less, Crucial has a reliable SSD available:

Personally, I chose Crucial.
