Jacksum supports 489 algorithms, including the most common cryptographic and non-cryptographic hash functions. Jacksum also supports the "Rocksoft (tm) Model CRC Algorithm" to customize your CRC.
Jacksum can perform a verification of hashes against a set of known hashes, and it can detect matching, non-matching, missing, and new files.
Jacksum takes advantage of modern multi-processor/multi-core environments, and saves time by hashing multiple files in parallel, and by computing hashes with multiple algorithms in parallel.
Output can occur in predefined standard formats (BSD-, GNU/Linux-, or Solaris style, SFV or FCIV) or in a user-defined format which is highly customizable, including many encodings for representing hash values, including binary, decimal, octal, hexadecimal with lowercase or uppercase letters, Base16, Base32 with and without padding, Base32hex with and without padding, Base64 with and without padding, Base64url with and without padding, BubbleBabble, and z-base-32.
Input data can come from files, standard input stream (stdin), or provided directly by command line arguments.
Jacksum supports many charsets for reading and writing files properly, and it comes with full support for all common Unicode aware charsets such as UTF-8, UTF-16, UTF-16BE, UTF-16LE, UTF-32, UTF-32BE, UTF-32LE, GB18030, etc.
With Jacksum you can also find the algorithm used to calculate a checksum, CRC, hash or find files that match a given hash value.

FreeFileSync https://freefilesync.org/ I have been a happy user for years and have made a donation too. - Source: Hacker News / 4 months ago
FreeFileSync messed up my pCloud database a couple times at first (causing disappearing files in the Crypto Folder, mirroring of the same files over and over again). Pcloud support provided an easy way to fix the database. To fix the root cause, one needs to exclude FreeFileSync's temporary files from the backup: pCloud Drive > Settings > Backup/Sync Exclusions, exclude sync.ffs_lock and *.ffs_tmp. Source: 7 months ago
As per Apprehensive_Arm_754 answer below, https://freefilesync.org is the solution to my particular problem, since it allows all kind of simple rules and logic to apply, so I can make sure that the copy only happens in one direction, and only ever by file date etc. Much appreciated.

It was me, I'd probably play around with setting up shared folders of preferences and plug-ins and whatnot on something like dropbox or Google Drive. There are various folder sinking tools on both platforms such as free file sync on Windows. Since they are two completely different platforms, I don't know how interchangeable some of the preferences or plugins would be. I haven't used a Mac in a 100 years. Source: 7 months ago
