Question:

Question: If I add memory will it help High Sierra function better?

So, I have 4GB installed and my memory cleaner consistently shows that I only have about 2 - 2.4 GB available....before I use a browser or finder etc. and then things really go to crap.

I can't use Facebook anymore or else it crashes. It also crashes randomly a few times a day depending on what app I use.


I can add another 4GB to = 8GB. Does adding memory help fix the crashes and slowness?? Or should I be looking elsewhere for the fix?


Thanks.

MacBook Pro, macOS High Sierra (10.13)

Answer:

Absolutely nobody is going to be happy trying to run a modern macOS (including your High Sierra) on 4GB of RAM.

It's very easy to determine if a Mac's performance is being constrained by available memory. Please refer to Use Activity Monitor on your Mac - Apple Support. If the "Memory Pressure" graph is frequently "red" your Mac would benefit from additional memory. If not, it won't. It's that simple.

Rule 1 of Macs is don't install junk. Uninstall your memory cleaner.

I suggest you use the program created by Etresoft, a frequent contributor. It will provide a snapshot of your system which we can analyze to possibly determine the cause of your problem. Please use copy and paste as screen shots can be hard to read. On the screen with Options, please open Options and check the bottom 2 boxes before running. Click “Share Report” button in the toolbar, select “Copy to Clipboard” and then paste into a reply. This will show what is running on your computer. No personal information is shown.

Hello astrophee,

The first thing to do would be to get rid of your "memory cleaner". Modern versions of macOS, including the latest version, High Sierra, are designed to efficiently use all of your RAM. Using some 3rd party tool to interfere with that design is only going to slow down your system.


You didn't say exactly what kind of machine you have, so it is difficult to give accurate advice. However, I can tell you with certainty that if you could upgrade the RAM on your MacBook Pro, then you can also probably replace the hard drive with an SSD. You will get a far greater performance improvement with an SSD than you would with a RAM upgrade. I am not talking about a percentage increase either. An SSD should make your machine run about 4 times as fast.


If you do open up the machine to install an SSD, then you may as well upgrade the RAM at the same time if you can afford it. But because I don't know exactly what kind of MacBook Pro you have, I can't tell you how much RAM you could install. Some machines are limited to only 8 GB RAM. I'm not entirely sure if machines of that vintage could or could not run High Sierra. There is no MacBook Pro that can be upgraded to 32 GB RAM.


Also, there is a comment above that claims a recommended download from a non-Apple site of a program that starts with E is infected with malware. That comment appears to refer to my software EtreCheck. I don't why that comment was made, but I can guarantee that EtreCheck is not packaged with malware. EtreCheck is packaged with caution about advice posted on Internet forums like this one. When in doubt, always ask for a second opinion.

Thanks for all the replies and suggestions...

I have a Macbook Pro (15-inch, Mid 2010). An oldie.

8GB is my limit and its an old hard drive thats sitting in here. So I will switch it to an SSD.


I looked up the links leroydouglas provided and am learning a lot about what memory and ssd's actually are and do and I am going to go switch up both very soon.

I am confident after researching these things that that is the definition problem.


Again thanks for all the quick responses! Appreciated.

Thanks. I have actually used Etrecheck some time ago for another issue and have found it safe and perfectly fine. No troubles for myself.

And I will get rid of the cleaner. I just assumed because its in the App Store that its okay to use the apps.
