Aha! Found an app on the Lumia 1520 that’s downloaded & is now installing Windows Phone 10.

Tried copying music to an 8 GB micro SD card on the Lumia 1520 but ran out of space, so I reformatted the card. I intend keeping this as my spare phone & travelling camera. I'll get a 32 GB card tomorrow. I also have to get the micro-SIM card from the current flip-phone cut down to nano-SIM size to suit the Lumia.

Needs as must when the devil drives. I can take the storage of this thing right up to 96 GB by adding a 64 GB micro SD card but the only one I have available is 8 GB & it may not be big enough.

I've just finished hacking Windows Phone 3.1.1 for Mac so the app will work on Sierra. It's now syncing around 1000 songs to the Lumia 1520.

Nope, the carrier is too slack to push through the update for older phones. It's on 8.1 & wotever vesrion of Internet Exploiter comes with that.

A fella who'd upgraded his & his wife's Lumia 1520s to Lumia 950 XLs sold me one of the 1520s today for $120, about 10% of its original cost price. Alas, the browser won't let me blurb here: there's no response to tapping the Send button.
Also unable to use Blurbybot because /register is out to lunch.

For some reason a couple of names in this article are familiar. http://www.mirror.co.uk/tech/thirty-year-old-prototype-mac-9832832

Driving home from a Mac User Group meeting. A bit over halfway home, back is rather more painful than normal. Sciatica being mean & nasty as well. 35 km to go.

It's all good. Money came through today.

Made a bit of an oopsie with the rebuilt backup drive. Both Time Machine & CarbonCopyCloner completed their backup duties but then I noticed I's swapped partitions, the clone of the 512 GB SSD was on the 1.5 TB partition & the Time Machine backup was on the 500 GB section, not what I had intended. I try to have Time Machine backups of at least 2.5 times the size of the boot drive.

Back to Disk Utility to erase the drive. It failed, the two partitions were unmounted & wouldn't come back up, no matter what I tried.

So I switched the drive to the MacBook Pro & erased it & redid the partitions as I should have done in the first place, hey, it was 4:30 am & I should have been sleeping.

Ejected the HD & reattached it to the MacBook Air. Set up backup apps to the correct partitions. Backups commenced on correct partitions.
