APFS Snapshots and Large Files

Howard Oakley:

Snapshots are more efficient than regular backups. If a single byte changes in a file, the whole of that file has to be copied in the next backup. Snapshots keep only the parts of the file that change, so that the original can be reconstructed. But over time and use of that file, the amount of it which has to be retained to restore its original state inevitably rises up to the limit of the whole file size.

[…]

If you have sufficient free disk space to include VM and other large files in backups and snapshots, then you don’t need to change their location or policies.

To maintain better control of backup storage, you should move VMs and other large files to a separate volume, and add the whole volume to the Time Machine exclude list, or disable snapshots on that volume in Carbon Copy Cloner.

2020 Mac Hardware Rumors

Chance Miller:

But the 14-inch MacBook Pro is said to be just one of the mini-LED products Apple will release in 2020. The others include a 12.9-inch iPad Pro, a 27-inch iMac Pro, a 16-inch MacBook Pro, a 10.2-inch iPad, and a 7.9-inch iPad mini.

Kuo doesn’t offer specific release dates for any of the products other than the iMac Pro, which he says is coming in Q4.

So the 13-inch MacBook Pro will finally get the fixed keyboard, but no word on the MacBook Air.

A Q4 iMac Pro release would mean about 3.5 years between the announcement and the first update.

This is not the pace we’d hoped for.

Update (2020-03-12): Mike Rockwell:

Just a month or two after I started using my [2018] Air, I started having issues with missed and duplicate key presses. I’ve sort-of lived with the annoyance until now because I didn’t have another suitable Mac available to use while my primary machine is out for repair.

Joe Rossignol:

Apple plans to release new MacBook Pro and MacBook Air models with scissor keyboards in the second quarter of 2020, according to a new research note today from analyst Ming-Chi Kuo, obtained by MacRumors.

Joe Rossignol:

Kuo said Apple plans to launch MacBook models with its own custom processors in the fourth quarter of 2020 or the first quarter of 2021.

MacSurfer Shutting Down

MacSurfer:

Not seeing a viable future with subscriptions, MacSurfer and TechNN will cease operations effective immediately. Please allow a few weeks to process forthcoming refunds. If need be, subscription inquiries can be addressed to the Publisher at the bottom of the Homepage.

Thanks kindly for your support, and thanks for the memories...

I’m sad to see this, as it was a great site for many years, and perhaps the best way pre-Twitter to find lots of stories from a wide variety of sites.

Dan Moren:

For many years, they were an invaluable resource, a manageable way to quickly see what was going on in the Apple world without having to subscribe to hundreds of sites and spend literally all of your time trawling headlines.

But as social media and podcasting grew in popularity and RSS and “visiting actual websites” ebbed, MacSurfer struggled to adjust.

Update (2020-03-12): Steven Sande:

It’s sad to see websites shut down for any reason, and it seem like some of the older, more established sites just aren’t making it anymore. […] Well, that list gave me a good look at the sites that are no longer with us…

[…]

That’s not including The Unofficial Apple Weblog (killed by AOL in February, 2015), MacCentral, Macsimum News, and Apple Daily Report — websites that Dennis and I were involved with over the years.

SETI@home Shuts Down

Lawrence Abrams:

SETI@home has announced that they will no longer be distributing new work to clients starting on March 31st as they have enough data and want to focus on completing their back-end analysis of the data.

SETI@home is a distributed computing project where volunteers contribute their CPU resources to analyze radio data from the Arecibo radio telescope in Puerto Rico and the Green Bank Telescope in West Virginia for signs of extraterrestrial intelligence (SETI).
