If you add more memory to your MacPro and keep the original memory in the slots but for some reason that memory isn't being read, It looks like tht memory is not compatible with the new memory. So, will keeping the memory in there mess up the system? Auto mode for graphics allows Windows to use more than 2 GB of Mac system memory for video purposes, while allowing Windows applications to use it when possible.***. Parallels Desktop for Mac.

I've got a last-generation black MacBook with a 2.4 GHz Core Duo processor and 2GB RAM. Parallels 4 is running all right, but holds the rest of the machine hostage in terms of performance, even though there's still available memory and processing power. What can I do to get more balanced performance for when I need to switch between Windows and OS X?

Just FYI -- In every case I have seen, you will see a performance gain in switching to Parallels 5..

But to answer your question, what applications are you running? That is a fairly important issue here..

But, with the 2Gb of RAM, you will want to probably allocation between 512 and 768 Mb of Ram. Defintely no more than 768. Please start at 512 Mb, and slowly work your way up to a max of 768. Microsoft excel 2016 mac shortcuts. Ccleaner professional serial key yahoo.

Why? You are basically reserving up to 1 Gb for the Mac OS.. Within the 1 Gb 'free', Parallels will consume some memory, leaving up to 768 MB of Ram for the Virtual Machine.

I was wondering if adding more RAM would help the stalls and poor performance of a mid-2011 iMac. It was working great until I upgraded to Yosemite and the newer Parallels.

If your machine is starved for RAM then it will be swapping pages of memory out to disk.

You can check this whenever you find your Mac stalling and performing poorly by opening Activity Monitor and checking the Memory tab. At the bottom of the window you should see a value labelled 'Swap Used'. If you regularly find a significant value against this then your Mac could likely use more RAM. Ideally you want this to say '0 bytes'.

The coloured Memory Pressure graph can also tell you how efficiently your RAM is being used (i.e. is your Mac constantly having to swap things in or out of RAM). From Activity Monitor Help:

Speaking from personal experience, Parallels (or any software that runs virtual machines) need a lot of RAM to perform well. https://modernintensive.weebly.com/blog/design-of-reinforced-concrete-structures-by-krishna-raju-pdf-download. Of course it depends on how much RAM you are allocating to your virtual machines. Ibooks mac cant download family sharing books.

Speaking generally, adding more RAM gives the operating systems more resources for managing applications in an efficient manner. However, with respect to using Parallels, I'll add the following:

I've used Parallels for a few years now, with both a mid-2012 macbook pro (8 GB RAM), and a 2014 macbook pro (16 GB RAM). As a rule of thumb, you want to share the following evenly between Windows and Mac: CPUs, Memory, and Video Memory.

By equal sharing of resources, neither operating system should be starved of resources, especially when you're using many applications on both systems at the same time.
