The current model supports a maximum of 16 GB. Buy the machine, and subsequently upgrade your OS. there is no need to wait for software to come out in order to purchase a machine that will support it.
- The new iMac is not as easy to upgrade Ram, practically not possible to do it yourself.
For now, the max is 16GB Ram. I think that when you now have 4GB and when you are not going to use new apps, that eat Ram (FCP, and th like) 16 is more than enough.
- Another few months and it will be delivered with Maverick. Until now it was not difficult to upgrade the OS one step.
- A difficult choice now is to decide between harddisk (500GB), Fusion Drive 1 or 2TB, SSD (500GB). The fastest is the SSD and (in my experience the best solution), the fusion drive is faster than the HDD, but different software, basically being a large buffer and a big hdd: read about that carefully.
In the meantime: your old iMac being slow may be bettered: download Etrecheck from www.etresoft.com and post the list here.
Not on the 21" model. That model is SEALED and can not be upgraded in any way, not even by Apple, after you purchase it.
You can upgrade from 8 to 16 GB. 16 GB is the maximum capacity. There are two slots in the 13'' model supported a maximum of 2 x GB modules.
Thanks for all the speedy and helpful replies, all very useful.
As for what, and when to buy, I see on another website (Mac Rumours Buyers Guide) that the current iMacs on sale (release date 2012) are to be replaced with new models on 30 November 2013. Or, is this information out of date and the current models on offer are the 'Newly' introduced models?
No one here has mentioned any of this, so I may as well ask as it may help with the speed of your older iMac.
First, if your iMac IS a 2007 iMac, the max. RAM it can take is 6 GBs of RAM.
You can replace one of the 2 GB RAM modules with a 4 Gb module from here.
Second, how full is your iMac's hard drive?
If your drive has below 20 GBs of free hard drive space, it maybe time to consider archiving and thinning out data from the iMac's internal drive.
How many applications do you run simultaneously in the background while working in another application?
When browsing the web, how many open windows or tabs do you have open at one time?
Do you run any antivirus software on your Mac? Antivirus software can slow down the normal operation of OS X.
Do you run any "crapware" like Mackeeper or any other type of "crapware" like so called hard drive "cleaning" apps?
All of this can contribute to generally slowness of a Mac.
Good idea, as I said earlier: "In the meantime: your old iMac being slow may be bettered: download Etrecheck from www.etresoft.com and post the list here."
The OP already has 4GB, see original post.
When it is a software that has the brakes on, we will see it when we recieve the Etrecheck list here. Especially AV will show up. Let's wait and see what the matchless OP wants to do.
How many responses do people need to give clarifying the fact that I was clearly wrong about the latest model. I know what configurable means. I was wrong. Move on. To the OP, I'm sorry if any information I gave you was misleading. Cheers.
OK, I have now run the EtreCheck as recommended and the list is very long, most of it means nothing to me, so here goes:
