Apple in fact re-uses the same SK Hynix ICs in its iPhones and MacBooks: if they were truly custom, we'd expect different DRAM. Is there a remote possibility Apple has some significantly custom RAM? Sure, but nobody has found any evidence and it's been a long time now. Now, binning is normal, but 1) binning only improves consistency to match the ideally fabricated IC (not meant to exceed it) and 2) how do we know Dell / HP / Lenovo don't bin their memory, but because of volume + competition they can offer much cheaper end-user prices than Apple? There is no special LPDDR5A that only Apple can use. Why? There is no other RAM available on the market. Even if Apple custom designs its DRAM PHYs (the memory controller interface within the SoC, which I think Apple could and would tune), it'll still need to communicate with JEDEC-standardized RAM. LPDDR4X / LPDDR5 ICs are commodity products. That is how it is supposed to be, for the less technical users out there who are the majority. It's all very reassuring that macOS memory management works so well without me having to intervene. But eventually, it will let it go and free it up. People start panicking when macOS does not always immediately free up memory right after quitting an app or two, but part of that is just how caching is supposed to work.if it thinks you might do that thing again soon, it wants to avoid letting go of the RAM cache too soon. I can do a bunch of work in Photoshop or a video editor and watch memory pressure and swap go way up, but after a few hours or at most a day after finishing that job, things have settled back down to normal and lots of free memory again after the OS housekeeper comes in and does some mopping up and trash collecting of no longer needed caches and swap files. This also happens on my current MacBook Pro which routinely goes 2 to 4 weeks between reboots. Sure, memory usage and swap goes up sometimes, but then it inevitably goes back down as, after a while, macOS decides it's time to dump all purgeable data and then usage and swap go back down. What I have learned from leaving it running for such long uptimes is that macOS does manage memory properly over time without needing a reboot, just like its Unix heritage suggests that it should. At times I have left it running for months, like I literally reboot it a couple times a year. It's 10 years old so it no longer gets software updates, so it never has to reboot for updates any more. I have a Mac mini used as an HTPC video streamer and OTA DVR for my TV, and it just stays on. Or worse, they think they need to run some kind of "memory cleaner" program they unnecessarily paid for. There are a lot of users who start panicking when memory seems to be "filling up" and think they need to restart their Mac now, or every night, or whatever. There are interesting things to be investigated and considered here, but on skimming your page I see zero evidence for even the slightest technical competence for doing so. This is even apart from somewhat dubious claims as to which apps are native on which platforms (is it "native" when a Windows app is compiled for Mac - or Linux - by linking in some massive "emulation" library?) Then there is the whole issue of how much address space has been allocated vs how many physical pages have been allocated. What counts as "memory usage" by ONE application is hardly a trivial matter on all current OS's given the extent to which pages are shared or compressed AND the extent to which auxiliary services for a particular app may be performed by various separate demons or helper apps. IN FACT looking at Monitor in detail, Fing's RSS is 255MB. To start with, in the screen capture below, my Safari is managing the neat trick of "using" more memory than the system has devoted to all Applications in total.Īnd there is no way Fing is using close to 8GB of REAL memory! If it were, I wouldn't put up with it for a second. It's the little things.įrom what I've read, Apple is certainly investigating adding Face ID for the Mac.ĭo you have any clue what is actually being measured by these claimed "memory" footprints, on either Windows or Mac? But are ~100px additional height that groundbreaking, either? Not really. I'd love to have Face ID on my next MBA: it's an elegant improvement for a common workflow. There's definitely a wonderful benefit to just sitting down and you're automatically logged in once you look at the camera. I've used Touch ID on my MBA and Windows Hello (both IR and fingerprint) on my desktop PC. Windows has figured out the optimal facial recognition user experience, IMO macOS wouldn't need to re-invent the wheel here. Click pay and Face ID authenticates you automatically.Move hand from trackpad to Touch ID and then tap.Ĭurrent Windows Hello / future Face ID flow:. You'd likely use the trackpad to click an on-screen prompt, where your fingers already are. You wouldn't need to use any dedicated key.
