Manufacturers of storage devices measure storage capacity using the decimal system (base 10). That's why the product packaging and online specifications include a statement such as this:
Certainly, Mac OS X El Capitan was published to the public in 2015 by WWDC and the keynote was released in 2015 to the public, and the first public beta version was released on July,9,2015, and Mac OS X El Capitan is the twelfth major beta version of macOS among the Mac operating systems. To check if OS X El Capitan is compatible with your Mac model, see the list of builds and versions of OS X. It is important that your Mac has a minimum of 2GB of RAM and at least 9GB of vacant hard disk space.

Alternative Method to Install Mac OS X Leopard 10.5 ISO If the installation procedure that we mentioned in the last section doesn’t work well for you, the following steps may be helpful.
1GB = 1 billion bytes, and 1TB = 1 trillion bytes; actual formatted capacity less.

Recent Apple Macs - Identifier Listings. The most common identifiers for G3 and later Macs are each listed below. For example, the MacBook 'Core 2 Duo' 2.0 13-Inch (Unibody) can be identified by its US Order Number (MB466LL/A), its Model Number (A1278), its EMC Number (2254), its Model ID (MacBook5,1), and its official 'Apple Subfamily' designation (Late 2008).
Some of the storage capacity of any storage device, including of your iPhone, iPad, iPod, and Mac, is used by its formatting. Other factors, such as the operating system installed on the device, use additional storage space.
The operating system of your iPhone, iPad, iPod touch, and Mac reports storage capacity using the decimal system (base 10), which calculates 1GB as 1 billion bytes. This is the same measurement system used on the product packaging and specifications.
iOS 10 and earlier, Mac OS X Leopard and earlier, Microsoft Windows, and watchOS use the binary system (base 2), which calculates 1GB as 1,073,741,824 bytes. This difference between the decimal and binary systems of measurement is why the reported storage capacity differs from the storage capacity on the product packaging or specifications.
The Disk Utility app might also show slight differences in storage capacity, particularly for solid-state drives (SSDs) and flash storage, because of the additional space used by the EFI partition, restore partition, wear-leveling blocks, write-buffer area, metadata, spare blocks, grown bad blocks, and factory bad blocks.

Mac OS 8 introduced several modern features while still supporting Quadras and 68040-based PowerBooks and Performas.
The six-inch “8” from that headline adorned the cover of the August 1997 issue of MacAddict magazine. Mac OS 8 had been released five days earlier, on July 26. Included on the magazine’s CD-ROM was a Mac OS 8 Preview Pack that consisted of technology demo presentations and Aaron, a popular shareware extension that let you make System 7.5 through Mac OS 7.6 look like OS 8.
Mac OS 8 was not without anticipation: Aaron had already been applying the Mac OS 8 look to System 7 for years. Because of this anticipation, sales were more brisk than expected. Internet retailer Cyberian Outpost sold more than 2,000 copies in the first four days.
What caused all this commotion? New features, especially the user interface called Apple Platinum.
Mac OS 8 introduced many new features for Macintosh users. The Finder changes are the first you’ll notice. These changes are deeper than just Apple Platinum; many features that are still part of the Macintosh today made their first appearance in Mac OS 8:
There are many other improvements that may not be visible at first blush. Here are some other features that made their debut with Mac OS 8:
While Mac OS 8 really is Grrrrr-8, it’s not an automatic choice for every Mac that can run it.
Due in part to its inclusiveness, Mac OS 8 has a much heftier RAM requirement than previous Mac OS revisions. While System 7.5.5 can be very usable with 16 MB of RAM, 32 MB is a better minimum for Mac OS 8.
Mac OS 8 also requires a great deal more disk space than earlier versions; the default install consumes 120 MB. Installation of larger, newer hard drives into these older Macs is becoming more common, so this isn’t as much of an issue as it was in years past. Still, the space crunch can be a problem for those who haven’t upgraded their hard drives.
Because of the increased RAM and disk requirements, Mac OS 8 is not a good choice for users of stock 68k Macs. While Macs as old as the IIci can run Mac OS 8, their original hard drives are too small for it to fit! Later Quadras shipped with hard drives as large as 1 GB, but the meager RAM that Apple gave them is not enough for Mac OS 8.
Despite these shortcomings, Mac OS 8 can still be a useful addition to your smaller Macintosh. Almost any system with 12 MB RAM and a 68030 will be minimally functional with OS 8. For access to CD-Rs burned by Mac OS X’s Disc Burner utility, only these bare minimum requirements need be met.
Even if your system isn’t big enough to run Mac OS 8 all the time, it can be helpful to keep a copy around.
To prepare for this article, I installed Mac OS 8.1 onto my Mac IIci, an unsupported 68030 Mac that runs at 25 MHz. I configured it with 20 MB of RAM and a 1 GB hard drive, and then I installed the default installation of Mac OS 8 according to Gamba’s directions.
Remember that this system is quite a bit smaller than both Apple’s and my recommendations. While I wouldn’t encourage anyone to run 8.1 on their IIci with less than 32 MB RAM, I found the system to be quite usable – and rather sluggish.
The Finder modernizations in Mac OS 8 are noticeable right away. For users with multibutton mice (such as the Kensington TurboMouse trackball), the contextual menus make for a lot less mousing-around to get to the menu bar. Spring-loaded folders really are as convenient as having your socks picked up for you. Mac OS 8 provides a great user experience.
The broad out-of-the-box compatibility with newer Macs is great, too. Right after the install, I can connect to and browse the Web using Netscape. I can exchange files with my Mac OS X 10.4 Tiger machine without the hassle of long directions and multiple updates.
Simply mounting HFS+ CD-ROMs instead of asking “Can you please reburn this as standard HFS?” is blissful.
While my IIci can’t do it, my Quadra can store hundreds of gigabytes on one partition. System 7 user’s “5 icons for one big partitioned hard drive” syndrome is no more.
All in all, I’d call my IIci with Mac OS 8 experiment a success.
For Quadra owners with RAM and hard drive upgrades, Mac OS 8 is a very convenient, modern choice. Users of heavily upgraded II-series Macs will also enjoy it. Even users with smaller Macs can find a reason to boot into Mac OS 8 from time to time.
Don’t forget that the RAM and drives for these older Macs can be gotten very cheaply from many sources, including eBay. If you want to run Mac OS 8 but don’t have the hardware, it can be gotten at minimal cost.
Mac OS 8 is not available for free download, but it can be found in all the usual places. One excellent source is owners of Beige G3 Macs; they shipped with Mac OS 8.1 on CD-ROM. Once again, eBay is also an excellent choice.
Once you’ve acquired a Mac OS 8 CD-ROM, the important 8.1 updater can be downloaded from Apple.
As either your primary system or on a secondary hard drive, Mac OS 8.1 deserves consideration by users of all but the earliest 680×0 Macintosh computers.
