I managed to get a oldish 3Tb Time Capsule off Carousell for experimenting. It was pretty alright for the first day until I got tired of the hourly loudish HDD spin up.
There must be a way to adjust the hourly backup frequency to every 6 hours. Given this is a oldish EOLed device, I also want to preserve its longevity – as much as i can.
To do so, determine the new backup frequency you want it to be, knowing the backup daemon reads in the backup frequency in seconds.
If you want to adjust to a 12 hour backup, the new number would be 60 seconds * 60 minutes * 12 hours = 43,200
For a 6 hour backup frequency, the new number would be 60 seconds * 60 minutes * 6 hours = 21,600
- Go to the macOS terminal app and do the following:
- Unload the backup daemon using “sudo launchctl unload /System/Library/LaunchDaemons/com.apple.backupd-help.plist“
- Change frequency on the the following file /System/Library/LaunchDaemons/com.apple.backupd-helper.plist using “sudo nano /System/Library/LaunchDaemons/com.apple.backupd-helper.plist“
- Look for the line that says “<key>Interval</key><integer>3600</integer>“, change the integer value to the newly calculated value above without the comma.
- It should read the following with a 12 hour backup frequency “<key>Interval</key><integer>43200</integer>“
- Save the file with Ctrl-X.
- Then reload the plist using “sudo launchctl load /System/Library/LaunchDaemons/com.apple.backupd-help.plist“
You will only hear the HDD storage startup only twice a day, and extend the HDD’s life!
PS – The above was verified to work on Mojave.
PPS – You will need to do this for every macOS device.
Got the news today about the next iteration of RPi4 memory bump from 4GB to 8GB. Still hot enough to fry an egg.
The new computer now cost USD75 (S$107 at sg.element14.com).
I got stuck resetting a router’s administrative password. While I had the required Cisco cable (console to serial) and a Usb to Serial adapter, Windows 10 wasn’t too happy with the Usb to Serial adapter I had.
Windows 10 said the Usb to Serial adapter was too old and wanted me to “CONTACT THE DEVELOPER”. No kidding, that’s what was written on the Devices page.
Switching to the MBP, I connected the Usb end of the Usb – Serial cable and did a
And I got a response from the router immediately.
I’ve been on the MacOS platform for over 8 years now and am quite pleased with Little Snitch. I’ve got to look for another one which works with Windows, now that I’m switching over to Windows 10 for work. These are some which I have found.
From what I’ve read, it appears NetLimiter 4 is the only one that allows you to allow/deny individual connection, like Little Snitch. I’ll be installing it to test out. The screenshots on the Netlimiter page makes me just want to head back to MacOS. 🙁

Hath the blockchain euphoria finally died a quiet death?
I’ve been saying this to 1. customers, 2. tech friends, 3. lesser tech friends, 4. non-tech friends. Not one believed me apart from the Vandy tech gang (where the real tech people are).
Hope the SG govt didn’t throw in good tax payers $ into this slow database.
