I'll be posting a follow-up article on how we tested the three notebooks so you can also run the same tests to check your own thermals.
I actually was able to get some hands-on time with three MacBooks Pro to do some testing: a 2016 Skylake i7, a 2017 Kaby Lake i7, and a 2018 i9 Coffee Lake. If the testing being done is in fact under normal conditions using real-world applications and if the reported clocks are accurate, then the 2018 MBP might have a cooling problem with the i9 CPU. The CPU is then forced to reduce the operating frequency to below the advertised base clocks in order to protect the CPU from damaging itself. This means that the cooling system is not dissipating the heat on the CPU sufficiently under certain workloads. This is the classic definition of thermal throttling. The claim is that under normal operating conditions, using prolonged CPU intensive tasks, the MBP is lowering its frequency to below the 2.9GHz advertised base clock speed. It's this last aspect that some people are claiming that the 2018 i9 MBP is failing at. Under normal operating conditions, the computer should be able to cool the CPU sufficiently too avoid this thermal protection mechanism from kicking in. If a CPU becomes too hot, the frequency can and will lower itself below the base frequency speeds if required until such time that the CPU is no longer in danger of overheating. One such mechanism is the CPU's ability to throttle or speed-down its frequency if the CPU starts to become too hot. Your CPU has built-in mechanisms that will protect it from damage. Fluctuations can occur as various computer tasks start and stop but sustained activity will average around the base frequency speed. Under these normal conditions, I can expect my CPU to run applications at this clock speed regardless of how long the program needs to run for and no matter how many cores it must use to complete a task. I shouldn't expect it to run at that base frequency even if I'm in the middle of Death Valley when it's 110 degrees in the shade.
I can expect my Mac to run at its base frequency while exporting a Final Cut Pro video when sitting on my desk in my office.
Normal operating conditions would mean using the Mac within a range of temperatures and elevations that a normal user would work in. The base clock speed is the frequency of your CPU to compute tasks across all of its cores at the simultaneously under normal operating conditions. This is not to be confused with the lowest possible clock frequency of a CPU when your computer is idle, which can be considerably lower. The 2018 i9 MBP has a base frequency of 2.9GHz. The base frequency is the supposed lowest speed the CPU should run when running compute tasks. The 2018 i9 MPB has no issue with this aspect of its computing prowess. That means programs that require a very short duration of CPU access and only require one CPU core, will be capable of reaching the highest CPU boost speed as advertised. The conditions are typically ones that favor single threaded burst activity. The boost frequency is the fastest clock speed the CPU will run at under very specific conditions. For example, the top of the line 2018 i9 Coffee Lake MacBook Pro has a boost frequency of 4.8GHz.

We hope you find this tutorial informative and definitely start setting up an alarm on your Mac. Otherwise, none of them work and you are not going to receive any alerts and notifications on Mac. In order to use any of the following techniques, your Mac must be switched on. On the left navigation bar of the web app, there are choices for a timer, a stopwatch, and the world clock. Click the Start button after you’ve completed all the necessary information. Set your alarm for a certain time of day using the hours and minutes menu. On the website, click the Set Alarm button, and a box will show up for you to fill out the information needed.
There is a free alternative available at, as well. Web programmes don’t often have access to your computer’s system settings. To make this work, make sure your MacBook isn’t muted. You may use an online web app instead of the Reminders app or Siri to set yourself a reminder. You can use the sleep feature to pause the alarm for some minutes which is not possible on the above two methods.
