I’ve an software that generates a major quantity of non-persistent knowledge throughout runtime, just for my use case, however not different customers.
The software program itself lacks a built-in mechanism to routinely delete this knowledge, as a result of different customers don’t have this want.
Subsequently, I intention to create a RamDisk to handle this knowledge. This strategy would serve two functions: minimizing put on and tear on my onerous drive whereas concurrently releasing up area routinely.
To attain this, I eliminated the appliance’s default knowledge listing and changed it with a symbolic hyperlink pointing to a listing on the RamDisk.
The applying’s knowledge paths are positioned at (for instance functions solely; not precise software names or paths):
~/Library/Containers/com.app.title/Knowledge/Library/Software Help/AAA
~/Library/Containers/com.app.title/Knowledge/Library/Software Help/BBB
~/Library/Containers/com.app.title/Knowledge/Library/Software Help/CCC
I used the next command is a shell script:
echo “⚙️ Creating ${RAM_MB}MB RamDisk...”
DEVICE_ID=$(hdiutil connect -nomount “ram://$((RAM_MB * 2048))”)
echo “⚙️ RamDisk system id: $DEVICE_ID”
DISK_ID=$(echo $DEVICE_ID | awk ‘/^/dev/{print $1; exit}’)
diskutil apfs create “$DISK_ID” RamDisk >/dev/null
echo “✅ RamDisk created at: $RAM_PATH”
To create the RamDisk
And by
ln -s /Volumes/RamDisk/AAA "~/Library/Containers/com.app.title/Knowledge/Library/Software Help/AAA"
ln -s /Volumes/RamDisk/BBB "~/Library/Containers/com.app.title/Knowledge/Library/Software Help/BBB"
to hyperlink the appliance’s authentic knowledge paths to the RamDisk.
The proprietor of this symbolic hyperlink is MyUsername:employees, and the listing inside the RamDisk is identical.
Nevertheless, I’ve seen that the appliance appears unable to write down content material to the symbolic hyperlinks.
I additionally tried altering the permissions of the foundation listing on the RamDisk to 777, nevertheless it did not make any distinction.
Here is my guess:
The applying’s knowledge path incorporates “Containers” , so I think that is macOS’s software sandboxing mechanism stopping the app from writing knowledge exterior the sandbox.
Nevertheless, RamDisk itself is not required by the appliance, so I am unable to use standard strategies to permit the app to write down knowledge to RamDisk.
Does anybody know the best way to resolve this concern? Or are there some other approaches that do not require a RamDisk?
I’m utilizing macOS 15.6.
A lot appreciated.
