Now has three presets to control speed and energy consumption of compression and decompression, together with complete custom control.
How to work out how many threads and which cores are needed to achieve a compression rate up to 1.7 GB/s, and how to estimate power and energy.
Provided in Archive Utility and three command tools, its LZFSE compression even supports APFS special files like clones and sparse files.
If apps control the Quality of Service, which sets how macOS allocates them to different processor cores in an M1 chip, how can we have any control?
By segregating macOS background tasks on Efficiency cores, M1 Macs can run user apps unfettered on their Performance cores. And that feels really fast.
How the M1’s asymmetric cores can run background tasks more efficiently, or deliver high performance, according to Quality of Service.
How can you compress and decompress small files faster? In AppleArchive, just send more of them for processing at the same time.
First full release of this free utility designed to help move apps and more using AirDrop, as it doesn’t put decompressed contents into quarantine.
A new feature in Big Sur, which provides ready access to fast, efficient compression and decompression. Here’s first look and test app.
