Not fun. Massive leg cramps for the last few minutes. No position is comfortable. Still in spasm. And, just quietly, agony.

Yep. It's all good. Mavrix & Snow Leo working on separate partitions. iPhoto put up a bit of a struggle but it works now.

Just heard a startup chime from the other Mac, maybe Mavrix has installed properly.

15 minutes for Mavrix now.

They do appreciate it. Before I bought the now-dead 2011 MBP, I owned the ver same Mac that I'm fixing up. The User group at the time I was selling the old one needed a reasonably modern Mac to run their lending library database & play a few games. It was to replace an ancient PowerBook Duo 280c which used HyperCard as the database. The MacBook Pro after I sold it to them used Delicious Library in place of HyperCard.

Mavrix installer reckons it wants 25 minutes more to complete the installation. But I'll just wait & see, such estimates tend to be wildly optimistic sometimes. Once, with the 2008 MacBook Pro, the Mountain Lion installer was stuck showing 19 minutes remaining and didn't advance from there at all over the next three DAYS. #ICanBeQuiteStubbornWithGettingMacInstallationsWorking

I'm adding Mavericks to a 2009 MacBook Pro on behalf of the Mac User Group. The trick was to get 6.4 GB of updates across to the new partition (it'll be a dual-boot, Snow Leopard & Mavericks) in a reasonable timeframe. The updates were on a USB 3·0 stick but the target Mac is USB 2·0/FireWwire 800 only.

But I have an adaptor cable with FW 800 at one end & SATA drive interface at the other, and another similar one with USB 3·0 instead of FW. Add a 120 GB SSD to the mix, now it's getting easier.

Copy from the thumb drive to the SSD via the MacBook Air, took about a minute for the transfer. Remove the SSD from the USB adaptor & connect it to the FW one. Plug that into the target Mac & initiate the transfer.

Only took two minutes to move the 6.4 GB updates across, was going to take longer over USB 2·0. So now Mavrix is trying to install itself onto the larger of the two partitions of the non-standard 320 GB 7,200 rpm HD in the old MBP.

At the time it wasn't expanding. Of course, now that someone who knows something about the system is available, the problem doesn't manifest itself.

Currently using three of the four USB 3·0 ports on the iMac plus 2 of the three USB 2·0 ports on the Logitech AudioHub (powered speaker/USB hub). One of the two Thunderbolt 3 (USB-C) ports is free, the other has a Thunderbolt 1-to-USB 3·0 & Gigabit Ethernet adaptor attached in turn to a T/Bolt3-to-T/Bolt 2 adaptor. Done this way I can connect USB thumb drives to USB 3·0 without pivoting the iMac to access the ports at the back.

In another week or so I'm receiving a 4-port USB 3·0 front-facing clamp-on hub.
