I have an old Mac Pro 4,1 workhorse. It has the ATI Radeon HD 4870 PCIe video card, which occupies the lower two of the Mac Pro's four PCI slots. It tends to overheat in the summer and fail, so I'd like to install a Fox 2 exhaust / extractor fan above it. Looks like the intake of the fan will...

Hey guys, I have a 2010 Mac Pro tower that runs my recording studio (2.66GHz Nehalem Quad Core). All I really use it for is Logic Pro X, and not really much else, asides from associated plugin software. A few years ago, it started randomly turning itself off. While working, it'd be just...

Hi! Since yesterday I'm having an issue with my Macbook Air Early 2015 with BigSur: it shuts down unexepectly. I can't work more than 2 minutes with it. I tried resetting the SMC. I also changed the battery last year. When I run the log in the terminal (as explained in other forums and pages) it...

I have had a MacBook Pro 2016 for around 3 years, although the battery cycle count is 309 I am getting "Service Battery". I routinely use it with an external (portable USB-C) monitor, an external SSD and and external HDD and two bluetooth peripherals. It struggles to start up with the monitor...

After three mostly glorious years, my iPhone 11 Pro Max - in the same case, on the same wireless charger (or wired in car using CarPlay) has stopped charging due to heat. Anyone else? No new apps; I don't have social apps running in background - only real battery/power draw is phone (not when...

It’s a business strategy only. I’m an Apple fan boy (>25 years) like most of you guys. I love my iPhone, iPad and Macs & buy every year new ones. But one thing really bothers me. Their constant emphasis on how important privacy is to them even they are not serious about it. A big claim. I...

Hi, Thanks to the help of people on these forums, a few months ago I upgraded my 27inch, 5K 19,1 iMac to core i9 9900K, 128Gb RAM & SSD for the ultimate Intel-based Mac. I then also had some help with creating a Windows 10 Bootcamp, on an external TB3-attached NVMe SSD. I have (had) a a Razor...

I've seen speed comparisons, but has anyone documented any differences between the power consumption of a 1TB vs a 2TB SSD on a M1 MacBook Pro (14" 10/24 processor)? Similarly, is there power consumption data for 32GB vs 64GB RAM?

I do have a technical question. What is the diameter of the power/internet plug of the 24" iMac with the M1 chip? I'm making a custom stand out of a old G4 Sphere base to mount a 24" iMac. And I need to know what size holes I need to make to route the cable trough it.

I am ordering an M1 Air that I intend to plug into an OWC ThunderBay and a Dell 4K monitor. Both the ThunderBay and the 4K monitor provide power through USB-C (up to 85W and 65W, respectively). I understand there is/has been an (older?) Apple support article stating that the Mac will only take...

Hi, I have got a Power Mac G5 running Mac OS X 10.5.8 and I have upgraded the original Pioneer optical drive to an NEC one that supports dual-layer DVDs. I'm trying to make a bootable Mac OS x 10.5 DVD and I'm using Verbatim 8x dual-layer DVDs and the disk utility says burn failed! I have rad...

MBP late 2018. i9 + eGPU.Monterey, 12.3.1 I'm stumped here. PMset (power management) is off the charts for the last 3+ months. At random times (and OFTEN) it's running at 90%+ of the CPU. It'll launch, run high, terminate and relaunch. I've removed everything, did an SMC and the PRAM resets...

Hello! Apple states that the Mac Studio’s maximum continuous power (draw) is 370 W. I assume this refers to a top specked M1 Ultra. Does anyone know the continuous power requirements of an M1 Max 32c GPU with 64GB unified memory? Thank you!

self-explanatory title

I was wondering if the Mac Studio has any option for handling power fluctuations. The only reason one would prefer a laptop over a desktop is because of sudden power outages - sometimes, very often in many cities of India - including metro cities. Almost everyone who uses a desktop has a 20 min...

I’ve been having issues with my 2009 Mac Pro. Where it will shut off randomly, turn back on, shut off, repeat.. I have a 2009 Mac Pro flashed to 5,1 with dual 3.43ghz processors (12 core) 32gb of ram, the original nvidia 512 GPU in slot 3 and an AMD RX580 in slot 1. Troubleshooting methods...

Hi. I have a 96W Apple USB-C Power Adapter that is making an intermittent buzzing noise at 6kHz every 2 seconds when charging my Macbook Pro with it. I have already gone through the replacement process (the agent would not hear a recording of the buzzing I took) but the replacement charger...

I have a Quad HDMI capture card in the top PCIe slot. The OEM version had a super loud fan so I removed it and replaced it with a pure copper heatsink. It's a lot better, but I still worry about the heat, so I want to add a couple of 40mm noctua fans to it. The only problem is, I don't know...

Just looked at the power consumption of the running cMP 5,1. That system consumes about 300W on average translating to 220KWh per month. This costs me ~$65 in CA. It is likely a little less when it sleeps. But I am going to start using my M1 MacBook Pro a lot more as my daily driver.

Hi guys, I'm looking to buy a new charger for my iPad Air 3. From the official documentation it seems that the max wattage for it is 18W (it has PD fast charging). But I came across this experiment here...
