    Hey everyone

    In th recent news of the new Mojave I've noticed that it's not gonna be supported on my aging 2011 iMac. Also lacking usb3 support on my iMac annoys me now.

    Now what is the best direction to go, should I buy new one now or wait until new release? Any upgrades you recommend that are a must with a new iMac ?

    I do a lot of photography on lightroom so must be good for that.

    This has been done to death in other threads - read around.

    Summary: if you urgently need a new computer, the 2017 iMacs are good machines, proven tech, and include features like expandable RAM (in the 27") USB-A, Ethernet and SD card slots that might disappear from any new design.

    If you can wait, its plausible that new iMacs will be released in October and, if so, these would probably include the new 8th gen 6-core processors - which would be a useful speed bump for multicore-optimised jobs. There is no guarantee if/when this will happen, though. Also - on recent behaviour - don't be surprised at price rises or "improvements" that don't please everybody!

    Since we're now in the middle of September, its probably worth waiting a few more weeks - the only risk being that if Apple releases a turkey or hikes prices, used/refurb 2017 iMacs might get scarce/expensive.

    If you decide to get a 2017 model: avoid the 1TB hard drive/fusion drive models - at least get a 2/3TB fusion drive (which has a more generous SSD component) or, preferably, go for the largest SSD-only model your budget will bear and add external drives for "bulk" storage: the big performance boost comes from having the OS, Applications, VM, temp. files etc on SSD.

    For the 5k models, get the standard 8GB RAM from Apple and add a third-party 16GB (2x8GB) kit to bring it up to 24GB (with an easy upgrade path to 32GB).

    Oh, and frankly, I'd give Mojave a few months and an update or two after release before taking the plunge - despite the beta program there's always some glitch or key piece of third-party software that needs updating when it hits the masses.

    how easy is this to do?

    The 5k iMacs (not the 21" ones) still have a little hatch in the back to get at the RAM slots. The new RAM sticks just clip in to the two empty slots. Its very easy - you don't even need a screwdriver. Official Apple instructions here:

    Sites like will let you look up the model of your machine and tell you exactly which RAM to buy.

    As stated, forget Fusion drive. Get the biggest SSD your budget allows. And 27" 5k screen is the only way to go.
