So i am new to manjaro and i was trying to install few kwin scripts from the setting, when i search i cant see the scripts i want, like latte and force blur. I cant see them in the store, i can only see few scripts to download. please help me.
Thanks in advance
Welcome to the forum! 
The thing is that latte-dock — which is still available from the AUR — is no longer supported in Plasma 6. The original developer never ported it to Plasma 6, and he chose to abandon the project when Plasma 6 became mainstream.
There have been rumors of someone wanting to port latte-dock to Plasma 6, but so far nothing more has been heard of that. But on the upside of things, Plasma 6 allows one to create a panel that largely behaves as if it were a dock — it’ll even disappear out of sight when an application window is too big.
As for the force-blur script, you no longer need that either. Plasma 6 has the blur effect built-in via its desktop effects settings. Just open up System Settings, select the “Window Management” page in the list on the left, and then "Desktop Effects". You’ll see it in there. 
So how can i customize now. like i want to create a mac like environment as my desktop is mac. and i am struggling with kde 6.
Ah, that is a very good question, my friend — and I share your taste.
Here’s an example screenshot of my Plasma desktop… 
There are two ways you can go about it…
The first way is the manual way, which is a little more involved, but ultimately gives you more control over what exactly you want to achieve. In order to know where to begin, you must first understand the different aspects to theming and customizing in Plasma.
Most people just install a global theme — which is the second way of doing things, but I’ll get into that again farther down — but Plasma actually has multiple different elements that you can customize, i.e. …:
The Plasma Style. This is the look & feel of your panels and your desktop widgets.
The Window Decorations. This is the look & feel of your window title bars — their appearance, which buttons you want on there, and whether you want those buttons to be on the left, on the right, or any combination of each.
The Application Style. This is the look & feel of everything inside of the application window. There is however a difference here between KDE-native applications (and additional qt-based applications) on the one hand, and gtk-based applications on the other hand — gtk is the widget toolkit used by the GNOME, Xfce, Cinnamon and MATE desktop environments, and it is still being used in different generations, i.e. gtk2, gtk3 and gtk4, with the first two having a very similar look & feel to one another, while gtk4 has a very distinct and different look due to its incorporation of libadwaita.
The Mouse Cursors.
The Color Scheme.
The Icons.
A special word needs to be said about item #3 above, i.e. the Application Style. By default, Plasma 6 comes with a small number of pre-installed application styles, of which the KDE default is Breeze — the others are popular older themes still supplied for compatibility reasons.
However, you can also install the kvantum package from the repositories if it isn’t installed already.
kvantum — which will appear in your system menu as “Kvantum Manager” — is an SVG-based theme engine, which comes with a number of inbuilt kvantum themes already, but you can also load additional kvantum themes in it, which — like all alternative styling components for Plasma — you can find at store.kde.org.
The kvantum theme I’m using in that screenshot above is called “Carl” and was created by a guy who goes by the screen name Jomada over at store.kde.org. The kvantum theme is itself part of a complete “global theme” under the same name. Jorge (Jomada) has created several of those, most of them named after characters from the movie “Toy Story”. But there are plenty of other great theme developers posting their stuff up at store.kde.org as well.
So, with all of the above in mind, you can download those individual components from store.kde.org, and use the “Colors & Themes” section of System Settings to apply the ones you like.
Or… — and this brings me back to the global themes — you can simply pick one of the global themes from store.kde.org, and then apply that.
Be advised however that you still need to make sure that you have kvantum installed from the repositories, because even if you download a theme that has a kvantum component, you will still need to manually load this component into the Kvantum Manager — it’s as easy as unpacking the archive and then pointing the Kvantum Manager at the name of the folder where you unpacked it. You can then further tweak individual elements of the theme by way of the Kvantum Manager.
Now, concretely with regard to your preference for a macOS-like theme, you will also want to make some modifications to your panels — installing a global theme can already do that for you, but this is not always flawless. So I would advise the method I myself have followed, and as I will outline below…
Assuming that you have not made any modifications yet, you should have only one panel on your screen on a fresh install, and it’ll be sitting at the bottom of the screen, floating a few pixels above the screen edge.
Right-click the panel and choose *“Enter Edit Mode”. You can then put the panel at the top of the screen and adjust its thickness. Remove the Task Manager widget from it, and add the Global Menu widget. You may also want to add the plasma-applet-window-buttons applet from the repository — it’s not installed by default — and the plasma6-applets-window-title applet from the AUR. Arrange the widgets as per your personal preference.
Once you’ve set up the top panel, right-click the desktop, choose “Edit Mode” again, and add a second panel, at the bottom. Set up this panel as “floating”, “dodge”, and adjust its width. Add the icons-only task manager widget to it, and perhaps a desktop pager — this will by default still be in your top panel, but it’ll be invisible outside of Edit Mode if you only have one virtual desktop.
Adjust the width and thickness of the bottom panel to match the content — there will be a setting for that. And then add your favorite applications to it by starting them from the menu and pinning them to the icons-only task manager.
Now that your system is already starting to look a bit more like a Mac, head over to store.kde.org, and start perusing the incredible offering of window decorations, kvantum themes, global themes, wallpapers, mouse cursors, et al. You should also be able to directly install them — either as global themes or via the individual sections of the System Settings — via the Get New… buttons at the top of the respective page.
One word of caution, though… If you’re going to download global themes from store.kde.org directly by way of a browser, then be careful, and only select themes that have explicitly been listed as compatible with Plasma 6 — the Get New… function should already filter those out for you, but it’s not perfect.
Also best is to only choose themes that have still recently been updated, because many people upload themes and then abandon them, with as a result that they have in the meantime become broken due to changes upstream at KDE in how the different Plasma components work together.
I think I’ve about covered the most important stuff by now, so the rest is up to you.
Edit per addendum: Here are some macOS-like global themes for Plasma 6 you might be interested in.
bro ur theme looks awesome and can u please helpme setup it.i can give u my email or discord or whatever. I mean two years back i used to have coolest ui and now i dont know how to do it anymore and most of videos on yt are outdated and not of any use
We can do that here on the thread, if you like, or on a new thread. That way, other members can also benefit and learn from the experience.
Just start by selecting a theme, and then we’ll take it from there.
sure we can do it here, so i want something really cool but like mac, or we can recreate ur theme
Plenty of choice among the themes I’ve listed above, my friend, and there’s more where that came from…
Take your time to check out the cool ones.
Sure, I’d be happy to share, but it’s actually an existing theme from the above site, which I have slightly modified to my own liking…
lets do carl look and feel, and i have already applied themes, ijust need help with navbars and docks as i have only used latte dock and its no more supported and its been 2 years i havent used linux. i am almost done with my theme just wondering what clock are u using on top panel. i cant find suitable, i used to use better inline clock but its not capatible with plasma 6 anymore
It’s the standard Digital Clock widget that comes with Plasma, but I have set it to…
Ask away.
The layout of my panels is as follows…
From left to right…:
Application Dashboard widget (replaces Kicker or Menu)
Window Buttons widget (plasma-applet-window-buttons from Manjaro repo) (set to be hidden unless the active window is maximized)
Window Title widget (plasma6-applets-window-title from the AUR)
Global Menu widget
Spacer (adaptive)
System Tray widget (showing kmail, octopi, strawberry, telegram-desktop and yakuake)
Clipboard widget
Notifications widget
Volume Control widget
Kate Sessions widget
Plasma Vaults widget (plasma-vault from Manjaro repo)
Dictionary widget
Spacer (static, just a few pixels)
Digital Clock widget
Spacer (static, just a few pixels)
Individual Core Usage widget
Memory Usage widget
The top panel is set up as centered and covering the whole width of the screen, non-floating, and with a thickness of 20 pixels.
From left to right…:
plasma6-applets-separator-git from the AUR)The bottom panel is set up as centered, with an adaptive width, floating, and as “dodging”, meaning that it will move down and disappear when the active window is too large — it will then reappear when the window is closed or when you move the mouse to the lower edge of the screen — and the panel has a thickness of 40 pixels.
I’ve also installed the Truly Maximized kwin script, which hides the window title bar when the window is maximized.
This works beautifully in conjunction with the plasma-applet-window-buttons widget. When you maximize a window, the window operations buttons will then appear in the panel itself anyway, so you no longer need the window title bar to be shown.
In addition to all that, I’ve also got six “hot spots” set up, so that if you move the mouse against them, they will trigger an action…:
Have fun!
Thanks buddy
