Once I implemented this fix I went from getting 10MB/s to getting over 500MB/s+ (both read & write) on my Mac laptop connected over Wifi.

On your Mac, go to System Preferences - Sharing - File Sharing. Click on “Options”, and select “Share files and folders using SMB“. Also, select the account that you want to share the files and folders from. Also, press Option and click on the WiFi icon on your menu bar, which will display the IP Address of your Mac.
When you mount the SMB share, it's available to your apps (ie, you don't have to copy it over to/from the Mac). I do the same on Windows as on Mac. I personally use SFTP more often than SMB. Filezilla is a great cross-platform client. Linux apps can run on a Mac if it's recompiled and you install all the libraries needed as well.

BEFORE/AFTER:

On MacOS 10.13.x I was getting terrible network transfer speeds from my Mac laptop to the network share being served by another mac. We were only getting 10MB/s which was not even enough to stream videos at 720p but yet on the iMac this external RAID array was attached to we were getting 200MB/s+ and could stream 2160p30 (4k) videos no problem.

Server serving the network share:
MacOS High Sierra (10.13.6), External 24TB RAID array in RAID 10.

Access your phone/device files with common softwares: MAC OS Finder, File Explorer, ES Explorer, VLC, Kodi etc. LAN Drive is a powerfull and easy SMB server - also known as SAMBA server - designed for filesharing. LAN drive is also a powerfull client to connect to SMB servers, and view/copy/paste files easily.

Client access the network share (SLOW):
MacOS High Sierra 10.13.4 (also happens in 10.13.5)

The fix:

Make the change temporary (without rebooting):

Open a terminal
Close and re-open Finder and see if the problem goes away. Also close and re-open your throughput testing app (in my case BlackMagic Disk Speed Test app) before testing again (required!). This setting for me was set to 3, changing it to 0 fixed it and then changing back to 3 caused it to drop back down to 10MB/s, confirming the resolution.

To make the change permanent (requires reboot):

Create/edit the file /etc/sysctl.conf
Add this line to the configuration file:
Save and close file (type “:wq” without quotes, then hit enter)
reboot computer
Open finder and your problem should be resolved.
If it is not, try the guide that shows how to enable vfs_fruit module for Samba, I believe this is only useful if the server hosting the share is NOT a Mac as it enables better Mac compatibility for Samba. You can also try installing Samba instead of the MacOS implementation of SMB.

The Mac laptop that was struggling I had tried multiple known fixes before this:

Disabling SMB Signing (smb_signing) and it did show it as disabled in the terminal but had no impact for me. I disabled on both server and client and reconnected the share and restarted all services.
Changing connection from SMB to AFP, reconnected share, no impact
The final change, disabling Delayed TCP ack, fixed it.

Duplicate files is a silent killer as far as your Mac is concerned. They have troubled you for the past years, and they might trouble us in 2020 as well. But how about getting rid of them for a new year’s resolution?

Duplicate files are shady. You won’t know their impact until you see a ‘Disk Space Full’ warning from your Mac.

As it happens, however, you cannot prevent macOS from creating duplicate files. When you add music into iTunes, for instance, duplicate files are created. The same goes for the case of Apple Photos.

On top of these, you will be adding duplicate copies of photos, documents, music and videos on your own. Think of those repeated file downloads as well. In short, your Mac gets choked with excess files the more you use them.

So, what’s the solution? Well, regularly removing duplicate files would certainly help you, and it’s certainly the way to go in 2020 as you would want a much cleaner and quicker Mac this year.

Quick navigation:

Benefits of removing duplicates from Mac

The biggest benefit is that you will be saving a lot of space and keeping you mac clean. Let’s consider this scenario: when you add around 2GB of music to iTunes, you are practically spending 4GB of space from the Mac. For a device that has 128GB or 256GB of onboard storage, that’s not easy.

Removing duplicate files would also help you organize your Mac in a better way. You will not stumble upon duplicate results when you are searching for a file. If you are someone who uses Spotlight way too often, this is great.

After making duplicate removal a part of our digital routine, we also observed better performance on our Mac. Naturally, when it has fewer files to index and process, the macOS system performs better. We believe that’s indeed a convincing reason.

Meet the best duplicate file finders for Mac

It’s not the best option just sit idle and go through individual directories. Developers know it, and that’s why they have built software to do that.

Duplicate file finders will analyze your Mac for duplicate files and organize them neatly. Once these duplicates are identified, you can just remove them with a single click. Pretty cool, isn’t it?

So, in a minute or two, you will have a more free, organized and well-performing macOS system.

As is the case, there are a number of duplicate file finders for Mac, we wanted to present you the best to help clear the clutter.

To do that, we had set up some basic criteria as well.

Easy to Use UI is a necessity when it comes to duplicate file finders. You must have an easy option to scan the Mac and analyze the results in the quickest time possible. Because you have to select which files are to be deleted, this is important.
The best duplicate file finder must work with iTunes and Photos. As we said, most of the duplicates are found in Photos and iTunes. If the tool can’t search inside the two apps, that’s a bummer.
Filter options are also great when it comes to these tools. Sometimes, you want to delete duplicates that are of certain and sometimes, you just want to delete certain types of files. In either case, you’ll have to use filters.
Search option also comes in handy. Sometimes, you know that there are certain duplicate files on a Mac. Using the Search function, you can find and get rid of these files in a jiffy. This would also come in handy while filtering files out.
Last but not least, we also looked for some additional features in the best duplicate file finder. It must have, for instance, file preview and custom-delete option. Both these will help you confirm that you are deleting the right duplicate.

With all these pointers in mind, we chose the following best duplicate file finders for Mac.

Gemini 2 – Best overall for most people
Tidy Up 5 – Most powerful for advanced users
PhotoSweeper X – For duplicate photo finder and cleaner

What makes the app great?

Gemini 2 is great for many reasons. It addresses the three main elements that make a duplicate scanning app great — a user-friendly app design, ability to scan and delete duplicate files with ease, and the integration with photos and media. Here, we will look at each of these factors to find out what they really have to offer.

Design

On the design front, Gemini 2 is well-recognized and has been a favorite for long. It was awarded the Red Dot Communication Award in 2017 in the Communication Design category.
