We take a look at what we learned from the weekend's fixtures.
New manager, same Rangers woes
Derek McInnes insisted Rangers "aren't as bad as people think" but they continue to show some of the traits that caused last season's downfall.
He changed his back four again for the visit of Hibs, but they struggled to keep their shape with new signing Vanja Dragojevic hauling Josh Kerr to the ground for a penalty as the errors continued.
Mistakes and lack of consistency continue to frustrate the Rangers fans.
Watching Youssef Chermiti being stretchered off after the club rejected a big-money offer from Turkish side Galatasaray compounded the misery.
David Gray admitted Hibs "rode their luck" at times, but they stuck together to back up their impressive midweek Conference League qualifying win with victory at Ibrox as the pressure continues to ease on the head coach.
Hogh silences Celtic critics
A £11m price tag meant Hogh arrived at Celtic with a weight of expectation.
The striker's debut did not go to plan as he missed a number of chances against Dundee, but he more than made up for them against Kilmarnock.
Three goals in 35 minutes on the new grass pitch at Rugby Park showed the Dane knows how to read the game and find space in the box.
Kilmarnock's woeful defence was helpful for the striker, with Benjamin Nygren and Luke McCowan also taking advantage as the Hoops moved top of the table on goal difference.
Neil McCann's side have lost their opening two Premiership games while shipping nine goals.
The manager wants his team to be open, but they will need to improve at the back quickly to avoid another season of relegation worries.
Victory for Vrancken
It has been a tough start for Wouter Vrancken as Hearts showed little sign of last season's form that took them agonisingly close to the title.
Defeats in Europe and a collapse at Aberdeen last weekend had many questioning his appointment. Then they faced Dundee United at Tynecastle Park and delivered the perfect response to a 6-1 hammering in Europa League qualifying.
Everything seemed to click for the Jambos in front of goal as they stood firm in defence.
Given this was a side missing six players through injury and suspension, the signs were encouraging.
Dundee United failed to build on their 1-1 draw with Rangers in their season opener, but the Tynecastle scoreline does not reflect their performance over the 90 minutes.
They had plenty of possession and created chances, but lacked that final touch to make the effort count.
Phillips shines for Saints, but for how long?
Maximum points and back-to-back clean sheets has made for the perfect start for St Mirren.
After his opening day double, Killian Phillips' penalty was the difference between the two Saints in Paisley.
The midfielder is attracting interest, and Buddies boss Craig McLeish has vowed to help him get the best move he can as he enters the final year of his contract. .
Newly promoted St Johnstone played with confidence after marking their top-flight return with a win, but lacked a cutting edge.
They had no shots on target in the first half, missed a penalty and hit the woodwork. Not taking their chances cost them after a solid start.
Dundee impress as Dons stutter
What a difference a week makes - after producing an impressive fightback to beat Hearts, Aberdeen stumbled against Dundee.
They were far from brilliant against the Jambos but they dug deep until the end, something they failed to do at Dens Park as the travelling support made their feelings clear with loud boos.
Steven Pressley's side won 2-0, but a bigger scoreline may have been a fairer reflection of the game.
Joe Bevan was brilliant - scoring and providing an assist - as they picked up their first points of the season after a narrow defeat at Celtic Park.
The sides meet again on Saturday in the League Cup. Pressley will want more of the same from his side, Stephen Robinson need a major improvement from his.
Steelmen remain unbeaten under new boss
Fears for Motherwell after the departure of Jens Berthel Askou are so far unfounded, with Alfred Johansson picking up where his predecessor left off.
The Steelmen are unbeaten under the Swedish boss in Europe and domestically, and a clean sheet against Falkirk will further boost confidence as they aim for another top-four finish this season.
Motherwell looked the more impressive in the opening stages, but the Bairns eventually hit their stride and managed to take a point at Fir Park.
John McGlynn has lost key players, but that performance will have given them a boost heading into their first break of the season.
