A couple of days ago the keyboards to two of my machines stopped connecting correctly via bluetooth. I swapped out the batteries but still now joy. I connected a wired keyboard and that works fine.
In more detail
When I switch the keyboard on it appears in the bluetooth preferences and displays a message asking for a passcode, however typing the numbers does not appear to register.
If I open up the bluetooth preferences I can see the keyboard and if I click the "connect" button again a dialog appears but will not respond to typing in the numbers.
I have a bluetooth trackpad which connects fine as do my AirPods. The fact that this has seemingly happened to two keyboards connected attached to two different machines is perplexing. Spent an hour with the Apple Genius Bar but no joy, they would not connect to the machine in the Apple Store which I guess means it is an issue with both keyboards.
Tried deleting the bluetooth preferences, restarting, taking out the batteries for a day…
Any other suggestions?
This is often a time of year when people do some spring cleaning. Of course it always too easy to delete something that you may need later so having a good backup strategy in place is strongly recommended.
I was reminded when I saw the article in Nature recently "11 ways to avert a data-storage disaster. Hard-drive failures are inevitable, but data loss doesn’t have to be" Link.
I have a couple of types of backup, an archive that stores critical versions of files, I have copies in Time Machine, an external server and I use Amazon WebServices to provide external storage.
The second runs every evening and generates a copy of the hard drives and stores then on Amazon WebServices
The final type is the every day stuff and for that I use Time Machine, this gives me virtually instant access to accidentally deleted/corrupted files, this is stored on an external Synology server.
I recently had to restore a machine from a backup and was delighted to be up and running in a couple of hours.
I just had a look at the new LG UltraFine 4K monitor for Mac, looking at the box (image below) with the Mac logo, it seems likely that Apple were heavily involved in the design
A single USB-C cable (included) provides up to 60W of charging power to the MacBook Pro. And three downstream USB-C ports (480 Mbps) offer additional connectivity and power to compatible devices and accessories. There are no other ports.
The new Apple laptops come equipped with only Thunderbolt 3 (USB-C) ports, I suspect the whole industry will standardise on USB-C pretty soon but at the moment there is obviously the need to support legacy peripherals. Fortunately Apple have put together a page describing most of the adaptors that might be needed. This includes standard USB, HDMI, VGA and Lightening cables. Remember up to six devices can be daisy-chained to each Thunderbolt 3 port of the MacBook Pro; and the Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter doesn't count as a device against that limit.
MacBook Pro (15-inch, Late 2016) delivers full Thunderbolt 3 performance on all four ports.
MacBook Pro (13-inch, Late 2016, Four Thunderbolt 3 Ports) supports Thunderbolt 3 at full performance using the two left-hand ports. The two right-hand ports deliver Thunderbolt 3 functionality, but have reduced PCI Express bandwidth.
MacBook Pro (13-inch, Late 2016, Two Thunderbolt 3 Ports) delivers full Thunderbolt 3 performance on both ports.
I needed to buy a new monitor and since Apple don’t supply one at the moment I spent a week searching through online reviews and then looking at a selection at various stores. Eventually decided to get the Dell P2715Q 27-Inch Ultra HD 4K LCD Monitor. Very happy with the selection I just hope Apple don’t announce a new monitor next week!
I should have noted that you have to buy a separate AmazonBasics High-Speed HDMI 2.0 Cable - 0.9m / 3 Feet (Latest Standard) Supports Ethernet, 3D, Audio Return . Also if you need a Mac compatible web cam, this one is highly regarded.
