Sep 16, 2019 The file cannot be executed. X: The file can be executed. S: If found in the user triplet it sets the setuid bit. If found in the group triplet, it sets the setgid bit. It also means that x flag is set. When the setuid or setgid flags are set on an executable file, the file is executed with the file’s owner and/or group privileges. This not-really-an-answer answer probably doesn't solve your problem, though the result is so astounding/interesting not to dump it in the comment section. I set up a virtual machine with Snow Leopard Server (10.6.8). After deleting (not just disabling rwx!) all wheel group permissions of /bin, /sbin, /private, /System and all subsequent files and folders as well as those of all relevant.

If the drive is MacOS Extended (Journaled) you can turn off permissions globally
if the drive is NTFS then macOS does not allow writing to the drive, and permissions are useless since they don't get read by macOS. You will need 3rd party software to allow writing, it has nothing to do with permissions, and if you don't need the drive physically connected directly to a computer running windows NTFS serves no purpose.
Functionality of 3rd party utilites are up to the 3rd party
and CleanMyMac is scamware, remove it with prejudice before it causes harm to your system.

In this chapter, you will examine the storage technology used by Mac OS X. Storage hardware like disk drives and RAID will be covered alongside logical storage concepts like partitions and volumes. You will learn how to properly manage and troubleshoot these storage assets and to manage storage security through ownership, permissions, and access control lists (ACLs).

Although personal computer processor speed has increased around one-thousandfold since the first Mac was introduced in 1984, storage capacity has easily increased a million times over. Compare 1984’s 400 KB floppy to today’s average desktop drive at 500 GB, which is roughly equivalent to 524,288,000 KB, or 1.4 million 400 KB floppies. Users have responded by moving thousands of pictures and hundreds of hours of music and video, historically stored in analog form, to the convenience and dynamism of digital storage. Likewise, enterprise customers have replaced filing cabinets and storage rooms with Redundant Array of Independent Disks (RAID) arrays and backup tapes. Even though the Internet recently changed our perception of what a computer is used for, it’s clear that the computer’s primary task is still that of a tool to organize, access, and store our stuff.
In this chapter, you will examine the storage technology used by Mac OS X. Storage hardware like disk drives and RAID will be covered alongside logical storage concepts like partitions and volumes. Naturally, you will learn how to properly manage and troubleshoot these storage assets as well. Finally, you will also learn to manage storage security through ownership, permissions, and access control lists (ACLs).
File System Components
Before you begin managing storage on Mac OS X, it is important to understand the distinction between storage, partitions, and volumes. Traditionally, computer storage has been defined by disk drive hardware. After all these years, disk drive hardware still maintains the storage lead, as it has moved from removable floppy disks to enclosed hard disks. However, other more convenient removable formats have become extremely popular as they have increased in capacity. This includes optical media like CDs and DVDs and solid-state storage like SSD, USB key drives, and CompactFlash cards. All are equally viable storage destinations for Mac OS X.
Without proper formatting, though, any storage technology is nothing more than a big empty bucket of ones and zeros, and consequently not very useful to the Mac. Formatting is the process of applying logic to storage in the form of partitions and volumes. Partitions are used to define boundaries on a storage device. You can define multiple partitions if you want the physical storage to appear as multiple separate storage destinations. Even if you want to use the entire space available on a device as a single contiguous storage location, the area must still be defined by a partition.
Once partitions have been established, the system can create usable volumes inside the partition areas. Volumes define how the files and folders are actually stored on the hardware. In fact, it’s the volume that is ultimately mounted by the file system and then represented as a usable storage icon in the Finder. Obviously, a storage device with several partitions, each containing a separate volume, will appear as several storage location icons in the Finder.
Partition Schemes
As mentioned earlier, drives must be partitioned in order to define and possibly segregate the drive’s usable space. Every disk requires at least one partition, but Mac OS X can support up to 16 partitions per disk. You learned the advantages and disadvantages of using single or multiple partitions in Chapter 1, “Installation and Initial Setup.”
Mac OS X supports three different types of partition schemes. This may seem excessive, but it’s necessary for Macs to support multiple partition schemes in order to boot computers using modern Intel processors, support older Mac drives, and use standard PC-compatible volumes.
The three partition schemes supported by Mac OS X are:

Obviously, if you have any additional drives formatted with APM or MBR, you will have to repartition those drives in order for them to be bootable on an Intel-based Mac. But if you don’t plan on ever using the additional drives as a system disk, there is no advantage to repartitioning. Also, you should keep MBR drives unmodified if you intend to keep those drives backward-compatible with generic PCs or peripherals.
Volume Formats
The volume format defines how the files and folders are saved to the drive. To maintain compatibility with other operating systems and provide advanced features for newer Mac systems, Mac OS X supports a variety of storage volume formats.
