The System Information app provides detailed specifications and other information about your Mac hardware and software, including your network and external devices. In some versions of OS X, this app is called System Profiler.
Choose Apple menu > About This Mac. This opens an overview of your Mac, including your Mac model, processor, memory, serial number, and version of macOS. To see the greater detail provided by the System Information app, click the System Report button.
Yubico YubiKey 5 NFC. Probably the best all-round security key. Brings together the ubiquity of USB. Operating system: Mac OS X 10.11 El Capitan or later: Video: Compatible webcam: Voice: Compatible microphone and speakers, headset with microphone, or equivalent device: Video calls and meetings: For a better experience with 1:1 video calls, we recommend using a computer that has a dual-core processor and 4.0 GB RAM (or higher). Hardware of the Macintosh (or Mac) is produced solely by Apple Inc., who determines internal systems, designs, and prices.Apple directly sub-contracts hardware production to external OEM companies, maintaining a high degree of control over the end product. Apple buys certain components wholesale from third-party manufacturers. The current Mac product family uses Intel x86-64 processors. Easily check which versions of mac OS, iOS, iPadOS, or watchOS are compatible with your Mac model or iDevice. Guide includes OS X 10.8.x to macOS 11.0.x.

To open System Information directly, press and hold the Option key and choose Apple menu > System Information. You can also use Spotlight to find System Information, or open it from the Utilities folder of your Applications folder.
System Information opens to a system report for your Mac:
Select items in the sidebar to see information about each item. For example, the Hardware section shows your Mac serial number, the Memory section shows how much RAM is installed in each internal memory slot, and the Software section shows which startup disk (boot volume) your Mac is using. You can use the Network section and Network Utility to learn more about your network.
To have System Information read your serial number aloud, choose File > Speak Serial Number.
To save a copy of your system report, choose File > Save.
To learn more about System Information, choose Help > System Information Help.
When writing the specifications for your Lion Server hardware, start with minimum requirements and then add on based on the number of users, type of use, and other specifications specific to your implementation. Here are the minimum requirements for running Lion Server:
- Computer: A Mac. Although you can hack non-Apple hardware to run the Mac OS X operating system, it violates the user license agreement.
- Processor: A 64-bit Intel processor. The oldest 64-bit processor found in Macs that support Lion is a Core 2 Duo. Lion won’t run on Macs with an Intel Core Sole or a Core Duo, which was the first generations of Intel processors that Apple used. (Older PowerPC Macs are also not supported.)
- RAM: 2GB RAM base. If you’re running Podcast Producer, you need an additional 512MB of RAM for each processor core. For example, if your Mac has two dual-core processors, you need 3GB minimum.
- Hard drive space: 8GB of free hard drive space.

The processor is, for the most part, determined by the Mac model you use. Macs with a dual-core Intel Core 2 Duo are slower than Macs with a dual-core Intel Core i3. Quad-core processors, such as the Intel Core i7, are faster yet.
The Quad-Core Intel Xeon processors offered in the Mac Pro are faster than the Core i7. (Core i5s come in dual-core and quad-core models.) The Mac Pro has the option for a six-core processor. (Logic and Latin would dictate that this is a “sex-core,” but the tech industry is wise enough to stay away from that one.)

The gigahertz (GHz) rating is less important than processor model and number of cores. It has meaning only when you compare two processors of the same model and same number of cores. So a 3.2 GHz Intel Core i3 is faster than a 3.06 GHz Intel Core i3.
As a general rule, use more RAM in a computer than the minimum amount of RAM required by the operating system. Some Macs can hold several dozen gigabytes of memory, which is more than most people need.

For hard drive storage, you need as big a drive, or drives, as you have data to store. Hard drive storage is relatively inexpensive.
