Is there a memory leak in that app? How to tell, and what you can do about it. Also notes about rare leaks in kernel zone memory, which can cause kernel panics.
Malicious software often relies on corruption and other problems with memory. Latest iPhones come with new hardware-based protection that’s also likely to come in a future M-series chip. Here are the details.
Why is an M2 Pro or Max preferable to an M1 Pro or Max? Is 8 GB of memory sufficient? Can I extend the internal SSD with an external drive? Can I buy and upgrade?
A problem from the first 128K Mac, virtual memory was available from 1987 but only with A/UX. It wasn’t really sorted out until Mac OS X, and now it’s all Unified anyway.
Is an M4 next week a better risk than the promise of a better model next year? Understand how to select the M4 chip suited to your needs, and specify your new Mac.
Equipping LogUI with controls to get log extracts from arbitrary periods in the past reveals two shortcomings: high memory use, and failure to release that.
If you are beta-testing macOS 15 Sequoia in a lightweight virtual machine on an Apple silicon Mac, beware […]
Managing memory and its problems was an important part of running Classic Mac OS, but everything changed in Mac OS X. Do we still need apps to do that?
Memory, from L1 instruction cache to main memory, and how it came to be Unified. Why the internal SSD isn’t like others, and why it’s so essential.
