Mac can be conveniently purchased from the Apple store and most of configuration allows you to upgrade the memory so that you don’t need to open the case and take the risk in using an incompatible memory which would cause system lockups.
- The 1.3 version of Memory Booster - RAM Optimizer for Mac is provided as a free download on our website. The most popular versions of the application are 1.3, 1.2 and 1.0. This free Mac application was originally created by Fresh Squeezed Apps LLC. The program lies within System Tools, more precisely System Optimization.
- The usual tips apply on a Mac, too — especially considering Google Chrome’s performance is particularly bad on Mac OS X. Try to minimize the number of browser extensions you use and have fewer tabs open at once to save memory and CPU resources.

The only thing is the upgrade from Apple store cost a lot more money if compared to the one that it purchased from a computer store. For example, an additional 2GB of memory cost $50 at Apple Store while it only cost less than $10 if you search in Pricewatch. If you’re willing to take the risk in adding extra memory in your Mac either to save money or perhaps you have a few lying around, it is best to run a memory test to make sure that the RAM is fully compatible and won’t make your Mac unstable.
Here we suggest 3 different methods to easily run a memory test on your Mac OS X including the latest Mountain Lion 10.8.
1. RemberRember is actually a GUI for the popular command line memory testing tool called Memtest OS X. Instead of typing commands in terminal, you can run the test by clicking a button. You are able to test a selected amount or all of the memory, specify the number of times the tests should run and also viewing of the log. Rember includes Memtest OS X in the package so there is no need to manually download and install the memtest. Running Rember will show a table displaying the detected memory on your Mac. Select the amount of memory to test, number of loops and click the Test button to start checking the memory. When the tests is finished, Rember will show the test results.
Rember runs in Mac OS X which means that not all of the ram can be tested due to a portion of RAM being reserved for housekeeping.

2. Memtest86+
If your Mac has a SuperDrive, you can burn the pre-compiled bootable ISO image of the Memtest86+ and boot up the Mac with the disc. Just press and hold the C key when starting up Mac to boot from the disc.
The good thing about Memtest86+ is it runs by itself without relying on the operating system, giving you a more accurate memory test result.

3. Apple Hardware Test
This is the recommended way by Apple to test your memory using their diagnostic tool. If you have an installation disc, insert the disc, restart your Mac, press and hold the C key. Select the language for the Apple Hardware Test and click the Test button to start testing. You can also tick the “Perform extended testing” option which would perform a more thorough test that takes considerably more time to complete. On the latest Mac OS X Mountain Lion, the Apple Hardware Test is already pre-installed and it doesn’t come with an installation disc. Simply boot up, press and hold the D key to start the Apple Hardware Test.
You can also see the amount of memory installed on your Mac at the Hardware Profile tab to confirm that the memory is correctly installed and detected. There are some Apple Hardware Test images that can be downloaded for older models. Do note that the Apple Hardware Test images are machine specific meaning that you cannot use the iBook version on a Mac Mini.

‘Closing all apps’ is an option which can be set or disabled in the Rember preferences.
ReplyI’m trying to test DRAM one bank at a time in mid-2010 Mac mini with 2 banks of 4GB Kingston DRAM each.
Rember run overnight on max cycles (255) showed when both banks were full (8GB total), there was a DRAM failure. But run overnight on max cycles (255), Rember is so slow it’s completed less than 30 cycles. I tried this twice.
Is it not possible to check one 4GB stick at a time? (Mid-2010 Mac mini standard RAM is 1GB module in each bank for total 2GB.)
ReplyI have several DDR3 DIMMs I want to install, but the memory timing is not printed on them. Is there an app for Macs that can tell you what the timing is on installed DIMMs?
ReplyRember doesn’t shut down existing programs… you do that yerself
ReplyRember is an amazing app! In regards to the comment above:
it closes all windows because to free-up whole RAM memory for tests.
It’s understandable that you must save your work before you open any diagnostic app.

Works great on latest 2019 iMac where Memtest failed and Apple Diagnostic Tool is a JOKE
ReplyRember
I ran this app and it closed all open windows and running apps without asking or warning me. That is bad software. Who knows what data I lost as a result, let alone time in reopening what I can remember was running. memtest does not do this.
ReplyHope this works well, thanks!

The simplest answer to the question: how much RAM do I need for my Mac is ‘as much as possible.’ You can never have too much RAM, whereas having too little can seriously affect the performance of your Mac. Sadly, however, it’s not quite as simple as that. Adding extra RAM, whether you do it when you buy your new Mac or you add it later, costs money, quite a lot of money. So the question of how much RAM to put in a new Mac is comes down to the balance between affordability and the additional benefit you’ll get from more RAM.
Why upgrade Mac RAM?
It used to be the case that adding more RAM would improve the performance of your Mac in almost every task. But computers have moved on since then. Better memory management, faster storage for caching files that can’t be stored in RAM, and blazing fast graphics processing units (GPUs) with their own dedicated RAM mean that the load on your main Mac RAM is less than it used to be.
Much of the work in generating frames for games, for example, is done by the GPU and its RAM. However, if you work with large images (bigger than, say, 100MB) or with huge databases or monster-sized spreadsheets, more RAM will be a huge benefit.
How to check your Mac's RAM usage
The quickest way to identify whether you need more memory is to check your Mac’s RAM usage.
One way to do that is to use the Manu App in CleanMyMac X. This feature will show you immediately how much free RAM you have and allows you to free up memory at the click of a button. It’s the easiest way to monitor and free up RAM. So, download the app (for free) and monitor your memory usage.
Alternatively, you can check the RAM usage manually:
- Go to your Applications folder.
- Open the Utilities folder and launch Activity Monitor.
- Click the Memory tab at the top and look at the Memory Pressure graph at the bottom of the screen.
- To the right of the graph, you’ll see a table. In that table, Physical Memory is the amount of RAM installed on your Mac.
Keep that window open while you work and check it now and again. If the graph stays green, there’s nothing to worry about and you don’t need more memory. If it’s green and yellow, there’s some pressure on your Mac’s RAM but it’s ok. If the graph is mostly red, however, it’s under serious pressure and your Mac’s startup drive is being used to store data that should be in RAM. This will slow down your Mac.
Just because the graph is in the red doesn’t mean you need to rush out and buy more RAM (assuming you have a Mac that can be upgraded), however. Closing browser tabs you’re not using will help, too. And you can free up memory by closing applications you’re not using or by logging out of accounts that aren’t in use, if you’re signed into more than one account.
To find out which apps, processes and browser tabs are using up the most RAM, click the down arrow at the top of the Memory column in Activity Monitor. That will order processes by how much RAM they’re using, allowing you to easily see who the culprits are. If you see any apps or web pages that are using lots of RAM and you don’t need, close them.
There are also third-party utilities that can report memory usage and ‘clean’ RAM when you close applications, so that the memory is freed up for use by other applications.
How can I upgrade Mac RAM?
Some Macs can be upgraded and some can’t. If you’ve bought a MacBook, MacBook Pro or MacBook Air in the last five years or so, you won’t be able to upgrade the memory in it. If you have an iMac, you may be able to perform a Mac RAM upgrade, depending on when it was made and whether it has free slots. You can find a complete list of which iMacs can be upgraded here.
The iMac Pro’s memory can only be upgraded by Apple or an Authorised Service Provider. Both the Mac Pro and Mac mini can be upgraded.
How much RAM do I actually need?
Adguard 1 5 3. So, after all that: how much RAM should you have fitted in a new Mac? For most users, 8GB is fine. You’ll be able to quite comfortably work on documents, edit photos and video and surf the web without any problems.
If you work on very large image files, databases, or spreadsheets, or if you really need to have lots of applications open at the same time, you might consider upgrading to 16GB. But you’d need to weigh the cost of the extra RAM against the benefit you’d notice.
What else can I do to improve my Mac’s performance?
The one and only reason for adding more RAM is to make your Mac run faster and more smoothly. However, there are other ways you can do this. Swapping a hard drive for an SSD, for example, won’t just boost startup times, but because macOS uses the startup drive to cache files, it will improve performance too.
Also, freeing up space on your startup drive will help, particularly getting rid of files you don’t need and that clog up your system. The best way to do that is to use a tool like CleanMyMac X. CleanMyMac scans your Mac for files it thinks you no longer need. These include system junk, Photos files that can be safely removed, and Mail attachments that can be re-downloaded if you ever need them again, and much more. By the way, the app is free to download, so give it a try!
As you can see, deciding how much RAM you need for your Mac isn’t straightforward. There are lots of things to consider. However, adding more RAM isn’t the guaranteed performance boost it used to be. For most people, the base 8GB that ships with current Macs is enough. If you do think your Mac could do with a performance boost, try the techniques described above before you rush out and buy more RAM.
